Field notes
- Fixed fading in/out of FieldStatus GUIText objects
- Clicking on the FieldStatus will now bring up GUI.Button things instead of more GUITextures
- On that note, MenuController doesn't do much anymore, but is still necessary
- Also, GeneralController has been renamed to the far more reasonable "FieldController"

Battle notes
- There is now a rudimentary battle system in place. Press "B" to open the battle menu, and "V" to close it. Only attack works right now
- When the schmoo is at 0 HP, the scene'll change back to the Field
- There are some corner-casing issues here (like pressing B again after the schmoo is dead), but we'll fix those eventually
