Enable asset compliation

- we fix the bootstrap-sass since the newer version
  seems a bit buggy
- we fix the glyphicons-* to app asset images so we
  can add them to the application.css.scss and override
  the asset-url
- we serve the static in production mode since
  we want to run on thin in production mode and
  nginx and apache will not do it for us
- remove ugly white space

Fix version of travis

we don't have ruby 2.0.0 on the vagrant and it
seems broken with ruby 2.0.0 on travis.

We should have both versions in sync so a successfull build
in Vagrant also succeeds in travis.
