Testing verion 19.08b on the way

[bvdp]

So, I've done some changes to the 'a' version and 'b' should be out later this week, depending on my schedule. So far, the following changes:

 1. In the -x code:
     The option doesn't need to be attached to the -x. So, -x NoCredit now works.
     Syntax for -xchords is now '-x Chords A B C'. No '=' or ',' permitted.
     Syntax for -xcheckfile=<file> is now '-x CheckFile <file>'. Again, no '='.

2. The track muting option (CHORDzMUTES) has been modified so that you can now skip the CHORD if one is previously defined. So, now, the line:
     C   Dm  zC  E
will be fine (previously you needed 'C Dm DmzC E').

Let me know what other goodies you are looking for.

Irritatingly no. 'z' and 'z!' were okay, but 'zAB' needed a chord name. Fixed that
