Modified the com_jk2 cvar to act like Ensiform asked. Should see a fairly noticeable performance increase with this commit. (note: not repsonsible if anything broke, was sleepy when coding)

(For real this time not a mega commit due to git derp)
Fix for issue #178

When doing G_RunThink for NPCs, it will skip the NPC_Think function and only run icarus when it hasn't reached the nextthink time.
Which means that the NPCGlobals such as NPCInfo will not be set for this run of icarus.
This causes null pointer crashes when icarus needs to access the npc globals.
