Fixed bug in GenericEditor
Changed fopen options
Added parameters to FPGAOutput
Added serialized CPMono fonts
Implemented error handling for audio device initialization

If there was a problem initializing the AudioDeviceManager, we show an
AlertWindow with Retry/Quit options.  Unfortunately, this doesn't fix the bug I
was initially trying to fix, because sometimes initialize() returns OK while
setting the AudioDeviceManager to null.
Error handling for when an audio device isn't found

Sometimes initialize() returns no error string, but will not find an audio
device, leaving aIOd == null.  This checks for that, and aborts the app with an
informational dialog window if so.
Fixed EditorViewport crash on keypresses

Before, EditorViewport would start accessing arrays on keypresses (specifically
the arrow keys) even when there were no editors.  This adds an extra check to
prevent this.
