REDCORE-249 add bootstrap3

Add bootstrap 3.2.0
Add fontawesome 4.2.0
Added new LESS files
Added new component.bs3.css which now load bootstrap3 + fontawesome4 in same file
Added additional methods to load media framework dependant on the extension definition, default is bootstrap2
Added separate layouts for bootstrap3 named layout.bs3.css and added suffix on jlayouts file to search for those layouts if bootstrap3 is selected as media framework
removed jqplot libraries
removed index.html files
I think you are absolutely right with redcore component layouts...
