Google Drive / Dropbox FilePicker Portlet.

I added a Google Drive / Dropbox FilePicker Portlet.  The portlet uses the FilePicker API to access Google Drive and DropBox.  Also, I am using bootstrap so I added that to be part of the  "resource sharing" config in pom.
Probably.  I started out with Google Drive and then Dropbox but forgot to re-factor the controller/ jsp.  My bad :)
