Major MT-32 emu overhaul based on KingGuppy's code.
o added configure option
o mi2 intro doesn't freeze anymore and has no sound glitches
o missing instruments in many titles are fixed
o numerous memory overwrite bugs are fixed
o code is cleaned a lot and splitted into many smaller files
o mt32.cpp went to backends/midi
o synced with upstream code
o reverberation fixed
* don't complain about File class wrapper :)
* all custom types are back
* #pragmas are to do
* maybe some indentation is wrong too
I prefer smaller commits, but this thing came in one piece.
