Replaced all instances of "her or she", "him or her", and "his or her", with "they", "them", and "their", or sometimes "that player". Updated verbs where appropriate.
"b" + "r" now changed to 'b' + 'w'. It's more straight-forward, and may cause perfomance improvements - character primitives allocation is faster and less expensive than string creation.
