From f02a0166f16a9745aab3e0139fa39ae97f66f23d Mon Sep 17 00:00:00 2001

Subject: [PATCH] add joy_axiskeyevents cvar which turns on engine-side
 emulation of arrow button events since not all drivers generate button events
 for movement axes. Also made wgl joystick code a bit more similar to SDL one.
