The audio onselect event had an errant bit of
logic that resulted in an exception - now fixed.
Also updated the Setup UI with nicer pictures
and some words that are more reflective of the
purpose of this software.
Added the ability to store the audio device
information within the ShortcutItem, and also
added the logic to the ShortcutForm to correctly
load and save the audio device settings. Also
coped with the edge case of when an audio device
is turned off or unplugged when the user edits the
shortcut... in that case we want to still keep the
old audio device settings as it is likely to be plugged
back in when the shortcut is actually run.
Part of the work through getting audio devices
into DisplayMagician, as it now scans the devices
and automatically selects the one in use currently.
You can also press the 'rescan' button to have it
update the list. This is the UI part done.
Next step is the saving the chosen audio device
to the saved Shortcut!
