Small Bug Fix Update

A small update just went live to fix a few bugs. The main one is the Undo bug which would cause cells to get stuck partially rotated if you clicked the undo button fast enough, pretty much requiring you to restart the level. This should be properly fixed now. Also fixed - the par time should be displayed at the start of the level, regardless of how you started it (from the level select screen or the level complete menu, and regardless of whether you resume a save or not). For such a small thing, it's actually quite complex... And finally - the Mosaic Complete sound should obey your volume setting now, so no unexpected booms if you were playing silently.
