#24 Fix EZ2Dancer gameplay issues plz?

[Anonymous]

I know that OpenITG is aimed to be a "DDR" simulator, but I guess it wouldn't hurt to ask.

There's a pair of issues in the Ez2Dancer gameplay that are really annoying. A friend is trying to work on them, but, the more minds working, the better:

- Doubles with P2: No input works. At all.
- Single mode (non-real): the lower sensors should work as the upper ones. Actually they don't.
