Modify develop to fix library browser3

Library browser3  appears to add library questions to sets but doesn't actually perform the operation.  
Still needs work but the other functionality seems good.

To enable drag and drop I had to move   js/vendor/jquery/jquery.js  to the version jquery-1-7-2.  
This seems to be a known issue with drag and drop compatibility of newer jquery and jquery-ui 
libraries according to the web.  It will require some research to determine what the best fix is.

This commit includes a lot of re_organizing the js directories.   It's conservative in the sense
that there are probably files in the js directory that can be removed (eventually) when we're sure they
aren't needed.  A few of them have been given permissions 000 to insure that error messages will
be generated if in fact they are still needed.  If no error messages show up we can delete those.
