Multiple characters and perf stats
Tiny update this time.
TICK is the number of milliseconds for main update loop
BUFF is when we process our graphics buffer and create the SDL commands to draw it
REND is when SDL actually renders to screen (it's so high because of VSYNC)
The first value is actually quite high right now, because I'm very wasteful and calculate shadowcasting and A* every frame even when nothing changes.
