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.
