[Tagging] River crossing grade

[Volker Schmidt]

Please do not introduce another grade scale - already enough trouble with
track grades.

Some immediate problems:

a river crossing where your body normally gets wet or you have to swim or
to take a boat is not a ford.
(The wiki page key=ford shows as option ford=boat)
