Clip cl_mouseAccelOffset at 0.001 to avoid division by zero
Setting cl_mouseAccelOffset to 0 will cause division by zero.
The modified ioquake3 included with OpenArena 0.8.5 has this change, which
turns off acceleration entirely in that situation:
http://git.debian.org/?p=pkg-games/openarena.git;a=blob;f=debian/patches/0010-CL_MouseMove-some-sort-of-mouse-acceleration-tweak.patch;h=d8953df5f0eb9807c63571ce370e4fbf7f6d9b33;hb=master
However, a more targeted fix would be to clip ridiculous values of
cl_mouseAccelOffset at a small nonzero value. I've attached a patch to do that.
