Remove unused function monty_copy.

Browse Source 
I wrote it for the sake of a test-system design I had in mind at the
time, but that design changed after I committed, and now I think
_even_ my upcoming test application won't need to copy MontyContexts.
So I'll remove the function now, so as not to have to pointlessly
write tests for it :-)
