Hopefully handle the "event overflow exploit"

There was an exploit where a keyboard would fire events quicker then
they could be consumed. This would lock the main game loop in the
SDL_PollEvent loop and block rendering until the key in this case was
released. Combning this with an attack meant that you could "farm" one
NPC for multiple kills and massive XP gains. Leaving the player at level
8+ on dungeon level 1. This fix should mitigate such shenanigans.
