Initial Setup

Added bundle. Registered with assetic, kernel, and style bundle.
Clicker Registration

Added ability to register multiple clickers per student.
Clicker improvements

Registration now works. Downloading the clicker registration file
works. And an update function has been created that removes clickers
that are registered to someone no longer in the class.
Registered with style bundle

Registered the clicker bundle with the style bundle so that links work.
Fixed bug in the style bundle where un expanded links wouldn't link
anywhere.
Better Registration

First name is no longer a required field. Orphan clickers are deleted
every time before someone registers a clicker.
