Issue14 - Note 1 focus

This will give focus to the note 1 field when accepting a source.  The keyboard can now be used to enter a letter instead of going through the dropdown (though the dropdown can still be used too).  Also note that pushing enter after entering a letter should cause the submit button to be pushed.  

This means the keyboard-based workflow should be quite smooth:
a - accepts current source, launch dialog
x - some note 1
enter - submit
and then you're on to the next image.

It would be good if you can verify yourself if this feels good or if there are other improvements that should be made.  So I will leave #14 open, and you can close it when you are satisfied.
