* Automatically stuff reference in commit message
So we probably want to track which edits were performed through the
Github interface, and this change automatically adds a label to the
commit message.
```yaml
<!--- Your description here -->
+label: docsite_pr
```
Eventually this allows to (on regular basis) list the changes from
documentation readers and process them in a separate process.
This is something I always wanted, a 'Edit on GitHub' button for module
documentation.
I also removed the additional statement in the footer with instructions
on how to edit the module documentation.
PS The links go directly into the GitHub file editor now !
* Docs refactor as outlined in https://github.com/ansible/proposals/issues/79. Moves content into 'guides'; refactors TOC; fixes CSS; design tweaks to layout and CSS; fixes generated plugin, CLI and module docs to fix links accodingly; more.
* Adding extra blank line for shippable
