Set up basic scroll bars to drawing window

See summary. Also added temporary code to make the maze
drawing be properly sized according to the maximum number of rooms.
(WIP)

Maze Class
----------------------
Added public constants that represent the maximum number of rooms
width/height wise.
Removed printing the question to the console

Removed getQuestion from the Maze class printing out the question to the
console, as it returns the question as a string.
Made output text area fields not editable

Made the output JTextAreas not editable, so the player can't type their
own words into it.

Also changed the ASCII output area in GameOver to be smaller, and
centered in the top of the GUI.
Clean up

Removed code that set the position of the GUI windows to be 50 pixels
from the top left as this is now handled by the centerOnScreen method.
