Patching app_chanspy to jibe better with what is documented. This allows for
a colon-delimited list of spygroups to be specified when calling the ChanSpy application
with the 'g' option. Prior to this, you could only specify a single group when using the
'g' option.

I also have upped the maximum number of spygroups to 128 and added a #define so that this
can be easily increased or decreased later.
