Similiar to SF #1632083, this patches matches two more variant names from the winboard v2 spec  to the FICS designation:
wild/0, wild/1 -> "wildcastle" 
wild/2 -> "nocastle"
Another change is to position.cc: the if before checkCastlingPossibility didn't check for WILDFR, which is obviously bad, as checkCastlingPossibility doesn't account for different initial positions than the standard one.
 wild/0 is the same as wildcastle, but with a single known initial position, so it's presented as wildcastle with the apporpriate FEN. FICS does the same for engines: http://www.freechess.org/Help/HelpFiles/new_features.html (1.25.5)
