Changes file for the 2025 series

This reflects changes to MMA since the release of version 21.09 (November/2021).

    Fixed the docs for the COPY and COPYTO commands. There never was a COPYTO command! TO and FROM are extensions to the COPY command. Opps.
    
    Added system variable $_PWD. This returns the current working directory just like the unix pwd command.
    
    An empty argument for DRUM TONE resulted in a infinite loop. Fixed.
    
    Added a bit of verbosity to the error message generated when defining a TONE or VOICE by a message if you have confused constants for the two.
    
    Added a ERROR command. Text after the error is displayed and compilation stops.
    
    Changed the parser so that when setting the scale offset to use with bass patterns - and/or + can be placed before the digit(s) as well as after.
    
    The options chord voicing options drop23 and drop23key had been commented out in 21.09 and 21.09.1.
    
    Fixed errors in the documentation build.
    
    RPITCH: Fixed some minor coding errors; added the BEATS option (very useful!).

    An error in common.py caused random crashes due to an undefined escape sequence.

    Several minor documentation tweaks and fixes.
