[MacGLQuake] Input Sprocket and Draw sprocket initialization order in GLQuake

[Avelino Santa Ana Jr.]

One thing I noticed with the inclusion of InputSprockets is that on multi
monitor setups the cursor disappears before you can select which monitor you
want, so I propose that in host.c Host_Init()  the IN_INIT() call be placed
AFTER the VID_Init() call.  I have done this in testing and I am once again
able to see the cursor until the monitor is selected.
