I checked with @fxn last night before making this change.
use default_options= instead of default to avoid confusion
Globalize2 is only compatible with Rails 2 so link to Globalize3 instead
Add quotes to Numeric Passwords to force string(Postgres)

If you have numeric password for your database, like below:
```yaml
development:
  adapter: mysql2
  encoding: utf8
  database: myblog_development
  pool: 5
  username: root
  password: 123456
```
you will get the following obscure error with unhelpful stack-trace

Looking [Can't convert fixnum to string during rake db:create](http://stackoverflow.com/questions/3765834/cant-convert-fixnum-to-string-during-rake-dbcreate), it seems lot of people have faced the same error.

so adding a note informing about numeric passwords seems like a good idea
Add quotes to Numeric Passwords to force string(sqlserver)

If you have numeric password for your database, like below:
```yaml
development:
  adapter: mysql2
  encoding: utf8
  database: myblog_development
  pool: 5
  username: root
  password: 123456
```


you will get the following obscure error with unhelpful stack-trace

repeating documentation for form helpers
`config.action_mailer.async` is no longer used
Add multipart: true to form for file upload.

I was slightly overzealous when removing this before.

Identified here: https://github.com/rails/rails/commit/ed78770b1a13788a5d3fcae484f34654de580bd5\#commitcomment-2281181
Document adding member route without the  option
remove Mass Assignment reference from Security Guide [ci skip]
remove Mass Assignment reference from Form Helpers guide [ci skip]
remove attr_protected reference from AS Core Extensions guide [ci skip]
Update railties/lib/rails/info_controller.rb

# :nodoc: the rails/info_controller
Update guides/source/routing.md

It's no longer necessary to delete public/index.html for the root route to take effect.
Remove deprecated Time methods from the guides [ci skip]

Don't use:
* Time.time_with_datetime_fallback
* Time.utc_time
* Time.local_time
Add #destroy! as a method that triggers callbacks
Output routes in :html format

By formatting routes for different media (txt/html) we can apply optimizations based on the format. We can include meta-data in the HTML to allow a rich experience while rendering and viewing the routes. This PR shows route helpers as they are used with the `_path` extension, it also has a javascript toggle on the top to switch to `_url`. This way the developer can see the exact named route helper they can use instead of having to modify a base. 

This is one example of an optimization that could be applied. Eventually we can link out to guides for the different columns to better explain what helper, HTTP Verb, Path, and Controller#action indicate. We could even add a route search box that could allow developers to input a given route and see all of the routes that match it. These are stand alone features and should be delivered separately.
