container-fluid

My first attempt to make htpc-manager fluid. All the modules that i have active seems to be okei (not qbittorrent as the tab are not scrollable but the other pr will fix that)

Some images might need some fine tuning. Like currently playing seems a bit small on the bigger screens (i think its a bit small on the 1300ish res aswell to be honest)

I have tested, sb, cp, stats, xbmc, newznab and sab.

Please test it and let me know what you think.
