Hit window visualization

[abraker95]

This comes with two different methods of visualization: In display and as its own thing

Visualizing hit window would help with knowing how various hit window settings affect the hit window. The visualization consists of a horizantal bar with color indicated hit (blue) and miss (red) windows, and a scale in ms below the bar.

In display hit window visualization can be done with Taiko and Mania (where position as a function of time is available). The bar is applied to every displayed note, so it is possible to see how player key events affect scoring. The bar is aligned horizontally for Taiko and vertically for mania.
