xfree86: add option "Floating", deprecate SendCoreEvents and friends.

Some devices should be initialised as floating from the start (e.g.
Joysticks and accelerometers benefit from this). Currently users use the
"SendCoreEvents" "off" flag for this, which isn't the most appropriate
naming.

Add an option "Floating", deprecate the others. Still parsed and handled by
the server.
