Fix #869
Autofocus every first field in forms and login.
Got rid of the breadcrumb. We don't really need it since with the tabs' header and the top menu bar we already have loads of information of where we are.
Refactored the admin stylesheet to be more consistent
Started removing less dependencies in favour of a compiled version of bootstrap (+ a rake task to generate them when the gem is deployed). Using less' JS parser isn't great and adding a dep to the project just for a few lines on the admin doesn't make sense.
