Saltfile feature initial parsers work
salt-run: colorize and strip rst when printing docs
salt-run: fixes for test failures
Allow for config settings to be overridden by a `Saltfile`

The order of configuration handling is the following:
1. If the user passes an option to the parser, that option rules.
2. If no option is passed to the parser and that option is set a
`Saltfile`, that option rules.
3. If none of the above and such option is set in the cofiguration file,
that value rules
4. As a last resort the default value rules

The format of the `Saltfile` is:

```yaml
<salt-cli-tool>:
  <confi-key>: <config-value>

salt-key:
  ssh_max_procs: 50
```
Make sure the user knows a Saltfile will be loaded.
Allow pillars to be cleared for all minions
This function was requiring an argument while `clear_mine` and `clear_grains` are clearing the selected data for all minions (or the targeted ones).
allow ext_dirs for grains
Change output of states.service to reflect changes

If a service is started, but already enabled, changes are now
reflected to the user.

Salfile
Strip leading path separator characters in a portable way.

Addresses the situation where get_id() ignores root_dir and always
looks for minion_id in /etc/salt/minion_id.

CRITICAL: State's don't send the environment...

CRITICAL: State's don't send the environment to render the pillar!

This is why `salt-call pillar.items` works and `salt-call state.highstate` does not.

There defiantly needs to be a test around this bug. I've tested this fix with both the `environment: dev` and ` `#environment: dev`. It works just fine.

Here is the corresponding code that does work: https://github.com/saltstack/salt/blob/develop/salt/minion.py#L283
