Resolves#15.
1) Cleared row count is marked before the onPieceLock method is called, letting the piece lock procedure react to the count of rows the piece is about to clear. (In practice, only 0 and non-0 will be different.)
2) The modes with bottom-row garbage will not advance the garbage counter when the piece is about to clear lines, as should be the case.
Also included:
3) Changed the Always O Randomizer to the Always Randomizer that takes which piece it should "always" produce as an argument in the constructor.
4) Fixed the torikan for level 800 in Phantom Mania 2. It should have been 4:45, not 4:40.
