Changelog for Billiards
* Migrated to Techne 0.2
* Added an experimentation mode.
* Added a proper replay feature now that Techne's simulation is deterministic.
* Added an arhiving feature to save individual shots and whole games.
* Added a proper GUI through which the game can be started.
* Fixed a couple of bugs causing slowdowns and freezes. Should be quite a bit more stable and faster now.
