this is a big one...

[Player] fix a warning [shakesoda]
[Player] Change combo coloring logic in course mode:
"PERCENT_UNTIL_COLOR_COMBO refers to how long through the course the combo color
should appear (scaling to the number of songs). (This may not be desired behavior,
however.)" Let me know if I should add an alternate way to specify course combo
color logic.  -aj

[other files including Player.cpp]
Update warp note logic; It used to be WarpFromRow=WarpToRow, now it's WarpFromRow=WarpLengthBeats.
They still aren't functional but I'm getting closer. Negative Stops are still not converted.
