Commit ID a66c73deef420104e74b6645ee60e20b37fd8549

Allow Position::init() to be called more than once Currently Zobrist::castling[] are not properly zeroed and rely on the compiler to do this at startup, but this makes Position::init() to set different values every time it is called! This is a bit odd, and although not impacting normal usage, can yield to subtle misbehaviour, very difficult to track down, in case we happen to call it more than once for some reason. I found this while developing tuning support and it took me a while to track it down. So properly init Zobrist::castling[] No functional change. Resolves #329
