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.
When I click on the dropbox icon, I get a JS error on this line (append child to element with id 'container') because the ID needs to be ${n}container.  I suggest passing the ID as a parameter into the dropboxLoad function.
