Subject: Resolve weird crash caused by Tetris inside ADLMIDI2 and other
 changes - Move most of inline classes methods into own CC file - Move Input
 into own header with own CC file to share it with the puzzle game - Created
 virtual destructors and resolved weak vtable trouble between of Tetris's
 classes - Remove static declarisons of Tetris class. Instead, let it be
 member of UserInterface - Fixed forgot note-offs while sorting events row
 with zero length notes - Fixed crash caused by unsafe access by reference to
 element of array that was modified/reallocated one or multiple times -
 Stabilize dealing with zero-length notes
