getroute: remove seed arg, document fromid, make default fuzzpercent match docs.

Browse Source 
seed isn't very useful at this level: I've left it in routing.c
because it might be useful for detailed testing.  Pretty sure it's unused,
so I simply removed it.

The fuzzpercent is documented to default at 5%, but actually was 75%.
Fix that too.
