Updated my untitled #lowrezjam roguelike.

Change log:

• Added a generating % to the generation screen.

• Sped up map & inventory sliding onto the screen.

• Fixed a problem with the inventory.

• You now click the inventory bag to close it.

• Improved the inventory Left & Right buttons.

• You can now click 2 squares from player but he will still only move 1 square.

• Updated some keyboard controls - Better to use the mouse at this point.

• Broke the inventory again & fixed it again - I think??!!

• Added potion usage. Using a potion will restore half of your lost health.
