Subject: Revamped iMuse and Player classes. Player now uses MidiParser to
 parse its data, which will allow it to parse other MIDI formats. To receive
 parsed data, Player now derives from MidiDriver to act as a "fake MIDI
 driver".

Miscellaneous upgrades and fixes to MidiParser, including the Smart Jump (which could not be tested before iMuse started making use of the MidiParser).

*** THIS IS A BIG UPGRADE! EXTENSIVE REGRESSION TESTING IS NEEDED! ***

This has been tested through the intros and a number of other scenes from MI2, FOA and S&M.

NOTE! This upgrade introduces savegame format version V19. Earlier version savegames will load, but the music will simply start over from the beginning. Only V19 and later games will properly restore the position of the music! Don't say you weren't warned....
