-Added grid sub-divisions up to 4, implemented for both mouse editing and number key editing
-Made a separate editor options window that contains:
*Amount of sub-divisions
*Snap to grid checkbox (now holding shift cancels out the check box)
*Play hitsounds checkbox
*Mute instrumental checkbox
-Added an option to make the colors of the arrows depend on their quantization instead of their direction (still needs to be adjusted to work on changing BPMs)
-Cleaned up the load code for the hud (static) arrow's animations
-Re ordered some appearance options
