Subject: disable joystick by default, and make joy_enable saved;
X-Git-Tag: xonotic-v0.1.0preview~2440
X-Git-Url: https://git.rm.cloudns.org/?a=commitdiff_plain;h=a2535521709ba873592188925ed1c9c170eb662c;p=xonotic%2Fdarkplaces.git

disable joystick by default, and make joy_enable saved;
add extension DP_QC_CVAR_TYPE that checks what type a cvar is (like, if the engine created it or the mod, or if it is saved)
will write dpextensions.qc block for it later, a start of its description is in mbuiltin.h in Nexuiz
