Importing tests from vgl

I haven't imported all of selenium tests yet, but I could use some help.  The tests in vgl seem to be out of date, and all of them have errors either when loading or in the mouse interaction.  As a result, I haven't written the unit tests yet, only the html.  You can build them by enabling selenium tests, setting up a web server, and browsing to `/test/selenium/vgl*`.
