[AD] old Mac OS X joystick

[Peter Wang <novalazy@xxxxxxxxxx>]

The copy of hidjoy-10.4.m is in the limbo state from Trent's initial
implementation of hotplugging, where it repeatedly repeated re-scans
joysticks and destroys and recreates joystick structures all the time.
Can someone revert it back to the version which didn't attempt hotplug
at all?

Also, the way that hidjoy.m includes hidjoy-10.4.m, does this mean if
you compile Allegro on a 10.5 machine, the binary will not load on a
10.4 machine, or that the joystick routines will fail to initialise?
