Ver 1.1--chill mode activated

I received some feedback requesting an option for a less hectic wire tripping experience, so for ver. 1.1 the major addition is the ability to select either "Fever Mode" or "Chill Mode" from the title screen (no idea where the idea for those names came from ;)). Chill Mode is actually a bit closer to my original difficulty tuning before I said what the heck and slashed/doubled a bunch of variables at the last minute before the original release. The ceaseless combo timeout is also more forgiving, so you don't have to worry about your buddy abandoning you prematurely.  If you want the "classic" experience, just go ahead and select Fever Mode. Your hi scores for each will be tracked separately, but don't worry, you can unlock all the buddies in either mode!

A few other little things:

- There were some rare reports of the sprite drawing function crashing the game by trying to call an empty variable. I put in a failsafe that hopefully should prevent that.

- Previously your hi score would only save after pressing "X" on the game over screen. Now it should save as soon as you reach the game over screen, so you won't lose if it you quit before returning to the title.

- Fever mode has been *slightly* tweaked to be a bit more forgiving

- Your prior save data should carry over--the old hi score will now show up as a "Fever Hi Score"
