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
