Subject: [PATCH] Configurable player pickup exp delay

Default vanilla value is to delay 2 ticks between picking up exp orbs.
Players only pick up 1 orb at a time, so even with setting this to 0
players still only pick up one orb every tick. However, setting this
to any negative number will pick up all orbs instantly.
