#18 Issue Resolution Commit
Notification Frame

pushing progress on the frame, now appears and disappears on a timer,
messages are queued
Notification Frame update

updated the notification frame to do full fading in and out. also added
a more specific import to make sure when the 'Frame' initializer is
called, it's the tkinter version (not ttk)
Boss GUI placement & main char emotions

The first boss is displayed graphically and some basic info on the boss
such as health and distance. The main character image changes to "happy"
when a hack is completed and "mad" when a hack is deleted. Also, some
images were not sized properly, so I resized them and changed the names
on the bosses as well.
