Brought in the documentviewer
Added z-index:0 to the document viewer

The document viewer top bar was appearing on top
on the overlays. This small CSS fix takes care
of that.
Cleaned up documentviewer dependency

Stripped out jquery and jquery UI as those are already in the page.
This reduces the size of the documentviewer dependency by about ~100KB

Addressed an issue in api.util.hideOnClickout which was using the wrong
jQuery variable.
Added jquery as a dependency to oae.api.content.js
Merge pull request #2590 from simong/documentviewer
