Subject: [PATCH] Added ignoreNumLock boolean per-screen option.  When true,
 NumLock is ignored on that client (it has no effect on the server).  This is
 useful for keyboards that don't have separate number pads and the user often
 uses the client's keyboard directly, when turning on NumLock interferes with
 normal typing.
