Changes to SBANK

-- Version 1.06

91.09.21 Added the -I ListFName option for translating bankfiles.  
         Removed the -Q option (too unclean for a command line utility).

-- Version 1.05

91.08.11 After experimentation, it was felt that it would be better to
         copy the Op0 parameters to the Op1 parameters instead of
         zeroing out the Op1 parameters (percussion mode).  Fixed
         many small annoying bugs.  Changed the format for parameter
         display.

-- Version 1.04

91.04.12 Made several performance enhancements.  Corrected error messages.
         Cleaned up the code.

-- Version 1.03

91.02.03 Facilitated zeroing out the carrier parameters when writing an
         IBK or SBI instrument (they have no way of storing PERC info)
