Fixed entities spawning in one single direction only.
Entities spawned with Hamgrenade now spawn at eye-level rather than on the ground.
Helps prevent entities spawning in walls and exploding before they're supposed to.
Changed the way the plugin reads info from the config.
Re-added Herobrine. (Those nuisances at Mojang keep removing him >.<)
Some of the entities don't work properly with the Pigapault and Hamahock modes due to the physics of certain mobs. Two known examples are Squids and Primed TNT.
