Subject: [PATCH] Catch spot dupes if they come in very quickly

Basically (apparently) there was a hole in the PC[16]1 handling where
it would accept a duplicate spot if it (physically) came in the same
second.

I'm not completely convinced that this is root of the problem but I can't
see a reason to have the code that was there in DXProt::handle_11.

+1. Fix dupe PC[16]1 (spot) coming in "too fast" for dupe filter to work.

 1. Make talk work. Note: this now works as the mojo branch originally
    expected - which means that it may (and likely will) flood route talks
