Fix Qt6 MOC compilation on some platforms.

That was super painful.  It seems that some of the Quackle types that
have custom operator==() give fits to the MOC compiler when those
types are used as arguments for slots and/or signals (or maybe it's
only when they're connected in a certain way...frankly, I never did
figure this out precisely to my satisfaction).  The compilers provide
very little help in resolving this problem.

Once I understood the problem, VS22 was giving me just the tiniest
morsel, enough that I could hunt down the offending slot/signal
(it wasn't even giving me the name of the slot/signal...just the type
it was trying to use).  I've changed all offending functions to use
const pointers to types instead of const references, and this makes
Qt happy.

I couldn't find any info on the web directly about this, but here's
the closest I did find, which suggests that this is related to
increased functionality in Qt6 regarding reflection.

This fixes my VC++22 x86-64 build.  Hopefully it fixes all of the
others, too.
