Fix some issues with AED.

 - When editing an action, you can now add more triggers to it.
 - Trigger Item dropdown now only contains the triggers that are compaible but not yet set rather than, all triggers except the last one you added.
 - If only a single TriggerGroup exists, automatically select it.
