ILS Tablet/Mobile Enhancements & minor fixes:

-ILS has optimized view for tablets/ipad
-ILS now works on smartphones/iphone
-Tab bar now adapts on window resize
-Activity stream changes (requested by UTWENTE) and "logout" activity is now logged.
-The text now has default (left) alignment instead of "justified"
-Not loading app.css anymore in a try to get rid of "legacy" code. Incorporated some useful classes in custom.js
