WIP to allow selection of video from other libraries.
- Need to figure out how to handle upload to support additional
  libraries
- Need to fix responsive styling given additional selects
- Need to refactor filter-block (formerly video-search and
playlist-select) to consolidate fields into single form.  Only want a
single submit button (if any)...and may want to remove labels or hide
when screen shrinks.
WIP adding support for searching of videos across libraries.
- Need fix to allow upload to current library
Update to allow upload to currently selected library.
Displaying username in logout tooltip, if possible.
authDomain is pointless...misunderstood how the API worked.  Thought
domain was parsed to find authentication source but this only works
with filtering (not direct basic authentication).
CSS tweak to hider.
Switched from SimpleAPI to internal API.
Fixed issue with arguments handling in base classes.
Scott demanded an Upload link alongside icon so folks don't overlook it.
Added notice in upload about autopublish configuration requirement for
immediate embed. Changed "Video" to "Media" in rendered labels (as
audio and images are allowed as well).
