Loads of changes

- Replaced all on-screen graphics with *.png files.
- Started work on rendering the GUI. (No buttons yet, it's a start to
get colored backgrounds to work everywhere)
- Fixed Item Animation.
- Removed a ton of obsolete nonsense that was related to Item Animation.
- Items will now Animate no matter where they are rendered. (Inventory,
dragged, on the map, hotbar anywhere)
- Slowly moving everything GUI related (Draw..... subs) to modGUI.
- Worked out more DirectDraw 7 subs, it is no longer being initialized.
(Note that this breaks all editors!)
- Tooltips are now completely rendered by DirectX8.
- The Character screen is now completely rendered in DirectX8, note that
the + sign buttons are still labels on the form. (They're just invisible
if you don't render them, so if you ever move these please more their
respective buttons on the form as well)
- Other stuff I honestly can't remember, this is a pretty large one.
