Initial replay parsing support.

- Basic implementation of viewing replays in the Game state.
- Added OsuReader class for reading certain osu! file types. (author: Markus Jarderot)
- Added Replay, ReplayFrame, and LifeFrame classes to capture replay data. (author: smoogipooo)
- Added 'keyPressed' parameter to HitObject.update().
- Added cursor-drawing methods in UI that take the mouse coordinates and pressed state as parameters.
- Added GameMod methods to retrieve/load the active mods state as a bitmask.
- Added Apache commons-compress dependency for handling LZMA decompression.
