Subject: [PATCH] changed the command mode subs thing to use anonymous subs

 issue PC19s (but do issue PC16s)

+1. Simplified command caching so it uses anonymous subroutines, you should
+also get error messages back on the console now when developing.
+2. Allow locally connected AK1A clusters that for some obscure reason don't
+issue PC19s to still appear as connected and allow them to acquire users.

 1. updated Minimuf.pm and show/muf.pl to the fixed versions sent to me by
 Steve Franke K9AN.
