Removed some unnecessary files from the repository.
Removed all precompiled assets from public/assets (they should be precompiled on Heroku).
Solved an error found in Chrome Developer Tools: "Uncaught Error: Popover requires tooltip.js". this means tooltip has to be loaded before popover.
Merge pull request #3 from rotev/master

Fixed a few issues. Deployment to Heroku seem to work now.
