Follow-up to #71.

- Fixed a major bug where two hit result calculations were being performed for each slider.
- Fixed a bug where hit circles/sliders were being drawn for a miss.
- Sliders now only expand when held to the end (as in osu!).
- Use the track position as the hit result start time for circles (instead of the object time).
- Added a 'color' parameter to Curve.draw(), rather than keeping an extra reference to the slider Color object.
- Renamed HitResultType enum to HitObjectType, and moved it into GameData.
- Removed some overloaded methods (not really necessary...).
- Other style changes.
