Bootstrap 3 compliance and responsive changes

Checked all documents through regular expression searches, to check and make sure that all classes were upgraded to Bootstrap 3.
Added .icon-white

As .icon-white was deprecated for Bootstrap 3, .icon-white is added so that icons that need to be white, can be kept white.
Icon renaming for Bootstrap 3

Renamed icons from their original icon* class to the new glyphicons* class names.
