Jin client for chess servers

Jin doesn't support the wild 4 variant and the uwild variant on FICS. (see
"help boards" for the uwild variant.) Also it can't start game which use a
special opening. (e.g. "match someone eco C50"). Because it is normal chess
with only a different starting position, it would be nice if Jin support
it. It only support such game, if it is examined, but you can't play such
games against any opponents. You get only the message from Jin, that it
doesn't support it, when you want to start such games. Because all games
string are of the form .*/.* (e.g. eco/C50) , it would be nice, if Jin
could parse such Strings and support such chess variants.
