Adding classes for easier theming

- Documentations
- Now using http://outdatedbrowser.com/
- Added initial-scale=1
- Added a compiled css file to SUBTHEME
- FileWatcher improvements
- Added optional asset_cache_buster :none to compass config

There are far better compilers out there then this php hackery.
The scripts are still available in the assetic branch.

Remove hook_sasson_alter;
Add a _settings partial to subtheme and a commented line in the main stylesheet;
