Issue:
Using wait=True in webhook.execute raises AttributeError
Title.

Here's the code (using eval command) and traceback in case.
```py
webhook = (await ctx.channel.webhooks())[0]
msg = await webhook.execute("test", wait=True)
```
```
Traceback (most recent call last):

    self.author = self._state.store_user(author)
AttributeError: 'AsyncWebhookAdapter' object has no attribute 'store_user'
```


Discussion:
This can be fixed on the user end by monkey-patching the webhook's adapter. Like this:

    hook._adapter.store_user = hook._adapter._store_user

The issue arises from the "store_user" mock being named incorrectly in WebhookAdapter. The implementation has an underscore, whereas the method being called doesn't.

Issue:
Flattening discord.Reaction.users returns the first 100 users over and over
Performing the following:
```python
users = await message.reactions[0].users().flatten()
```
on a message with 1.2k+ reactions returns a list of the first 100 users 12 times. I'm not sure if this bug is limited to `.flatten()` usage but it makes no sense to me considering `.flatten()` has no documented limit and `.users()`'s limit is automatically set to `None`.

Issue:
typing.Optional as last positional parameter is required
### Summary

When specifying a `typing.Optional` parameter as the last positional parameter (without a default value) for a command, that parameter is required and raises `MissingRequiredArgument` when the command is invoked without passing an argument for that parameter.
If there are consecutive `typing.Optional` parameters as the last positional parameters, `MissingRequiredArgument` will be raised for the first one.

### Reproduction Steps

```py
@commands.command()
async def repro1(ctx, arg: typing.Optional[int]):
    ...
```

```py
@commands.command()
async def repro2(ctx, arg1: typing.Optional[int], arg2: typing.Optional[int]):
    ...
```

### Expected Results

`MissingRequiredArgument` should not be raised for `typing.Optional` parameters, regardless of their position.
Instead, `None` should be passed as the argument(s) when not specified on command invocation.

Neither `repro1` nor `repro2` should raise `MissingRequiredArgument` when invoked without passing any arguments (e.g. `!repro1`, `!repro2`).

### Actual Results

`MissingRequiredArgument` is raised (for `arg`/`arg1`).

embed.to_dict broken in python 3.5.5/3.5.6
### Summary

Using embed.to_dict results in `ValueError: astimezone() cannot be applied to a naive datetime

### Reproduction Steps

Run the following code in python 3.5.5 or 3.5.6 (probably other 3.5.x versions too)
```import datetime

emb = discord.Embed()
emb.timestamp = datetime.datetime.utcnow()
test = emb.to_dict()

Issue:
[FR] Bulk role move 
### The Problem

There is no user-exposed method to bulk-update role positions, which can result in behavior like #2142 

### The Ideal Solution

This method should obviously be part of the guild class. Possibly `guild.edit_role_positions`?
The interface for this is kind of tricky-perhaps an argument list of (role, position) tuples passed to the method? 

### The Current Solution

Using the internal `http.move_role_position` method. 

### Summary

A method to bulk-edit role positions.

2. Read the asset using `reaction.emoji.url.read()`

Issue:
No support for animated invite icons, inconsistency between Guild.icon_url_as and PartialInviteGuild.icon_url_as
### Summary

- There seem to be no support for animated guild icons in invites. Trying to call `invite.icon_url_as(format="gif")` will raise an exception asking for a static format.
- `static_format` kwarg is missing from `PartialInviteGuild.icon_url_as` even though documentation states it is the same as `Guild.icon_url_as`: https://discordpy.readthedocs.io/en/latest/api.html?highlight=partial#discord.PartialInviteGuild.icon_url_as

### Reproduction Steps

```python
print((await bot.fetch_invite("discord.gg/python")).guild.icon_url)
# https://cdn.discordapp.com/icons/267624335836053506/a_0409ea649c9eb2aaaf3a5531a80a2528.webp?size=1024
```
Changing extension manually to `.gif` returns a valid icon.

### Expected Results

gif icon to be returned by default.

### Actual Results

webp icon is returned, it's impossible to get gif version.

[Commands] Using a typing.Optional[] converter in a commands.Greedy[] one
### Summary

I tried making a command with an argument like
`cmd(ctx, arg: commands.Greedy[typing.Optional[int]])`
(actual command and types not shown, but they work on their own)
However, the bot gets stuck in an infinite loop in Command._transform_greedy_pos().

### Reproduction Steps

I had a typing.optional[] type in a command's commands.Greedy[] converter. Similar to
`cmd(ctx, arg: commands.Greedy[typing.Optional[int]])`

### Expected Results

For this example, if I had a command like
`>command str 1 2 str 3`
arg would be passed a value of
`[None, 1, 2, None, 3]`
since the strings would get converted to `None` under the typing.Optional converter

Discussion:
This should probably just error out since it doesn't make sense.

Issue:
Member.joined_at is incorrectly documented
Hello!

### Summary

The documentation for the `Member.joined_at` attribute appears to claim that it gives the timestamp of when the member joined the guild *for the first time*.

https://github.com/Rapptz/discord.py/blob/ae1ec8072f9ef26acec107824eed42fdbb897cc2/discord/member.py#L150-L152

This appears to be untrue; it looks like the attribute gives the timestamp of when the user in question has joined *most recently*.

Here's a short snippet to demonstrate that I can make it give distinct values for the same guild & users id combination.

The Discord API docs only annotate the attribute as ["when the user joined the guild"](https://discord.com/developers/docs/resources/guild#guild-member-object-guild-member-structure).

### Duplicates

When searching for duplicates I only found this old PR addressing this issue that got closed: #882.

I'd be happy to open a PR for this.

I hope it's ok that I didn't follow the markdown template, I felt it wasn't fitting for this kind of issue.
