Display class displays simple tile.

Using java swing. Run the Main.java to see what has been done so far.

Used the absolute path from my computer unfortunately. Change in
Main.java for testing.
ImageRegistry now strings to images

Changed to HashMap<String, Image>.

Constant time operation.
Getters & setters & TODOS

Added some todos for later.
Updated GUI with working prototype

Prototype of the GUI. Contains a menu bar with several example items.
Only the quit item menu works.

Added two new components: Console and Status bar.  Both have custom
method for display. Capped the console to 200 messages. Both have
scrollable components.
