add contrib/ladder_to_msc.py

Typing mscgen diagrams, I am hugely annoyed by having to type '[label="..."]'
all the time.

Also, IMHO the arrows have been chosen in an unintuitive way: in mscgen, '=>>'
is the normal arrow, and '->' is a half-headed arrow, etc. I would like to use
other arrow symbols.

Hence, add script to convert my personal favorite ascii format for message
sequence charts to mscgen format.

See an example in ladder_to_msc_test.ladder.
