- Made everything 16:9 friendly
- Added Walls to arena scene

assets -> create -> new potion/armour

This reverts commit fc0f1ccb.

Fixed the different screen size issue (during play mode, looks silly
during scene view though)

Rebuilt the tree with more decisions, funky stuff was goin on

*bugs:
unsure why buttons are skewing size, can't figure out how to make them
all the same regardless of text length in each.....
- will have to make the weapon choice a permanent change through static
variables - but i have to go eat supper so i'll figure that out later
lol.
