- Added a filter for unpatched/null level channels (so you don't stare
at 512)
- Added an import from Hog 2 option.
This isn't really a full import as it only supports Desk Channels but
the framework is there to fix it. This allows it to act as a backup
console for hog2. It does not support Channel Specific timing yet (but
that's an easy fix).
- Added some AJAX callbacks to make sure this refreshes properly.
