Summary: Minor problems in native MT-32 mode

Initial Comment:
1. The original ROLAND.IMS reverses pan directions, 
ScummVM does not.
2. Incorrect Reverb handling: During MI2 Introduction 
Tune, "LeshBass" and "Elec Org 2" should be without 
reverb. A part's reverb information is stored in byte 2, bit 
2 (0x02) of a part's "part_alloc" sysex (cmd 0).
3. Incorrect Panpot handling in Woodtick, Wally's Room 
etc. For example, in Wally's Room, "Pizzicato" should play 
on the right, however, in ScummVM, it always plays 
centered. The correct panpot information is stored in 
bytes 07 & 08 (upper / lower 4 bits) in signed format, i.e. 
0=center, 0xc1 (= minus 0x3f) = left, 0x3f = right.
4. Collapsing pillars on Dinky Island: incorrect pitch bend 
range handling (plays as 2, should be 12). The correct 
bend range information is stored in bytes 13 & 14 (upper 
/ lower 4 bits, decimal).
