Fixes#449
Tkinter (used by aa-notify) needs the $XAUTHORITY envvar to start but on
some systems (e.g. OpenSuse), sudo clears it. This change add a
--xauthority command-line option to set it explicitly, so aa-notify works
under sudo.

Known Bugs:
Will allow multiple letters in the () due to translation/unicode issues with regexing the key.
User input will probably bug out in a different locale.
