Support for Eat My Dust (#4)

* Support for Eat My Dust
Zombie Alert manager is stubbed.
Added helpers to allow for weapon MMO.
PlayerData for Eat My Dust

* Zombie Alert Added
* Fix Zombie Alert Timing
* Honestly should probably catch this exception [null room in PM handler]. I foresee it occurring very commonly. While it shouldn't halt the server (except in visual studio debug), it's annoying to see.
