Bootstrap JS, assetic, form rendering, portfolio

Bootstrap: Renamed one JS file to make sure they get included in the
right order (it was going alphabetically, even if I just did one at once
Form Rending: Made it include form.js in BottomScript (so validate will
have loaded already) in the form view helper
Fixed cache path in global assetic file
Added hover function to logo and made a base.js
Moved head JS files to /head subdirectory
Deleted duplicate modernizr file
Several changed to Assetic config
Different styles for portfolio page
