New version of spawn, etc. data

[Drawde]

This version is compatible with EQEmu 0.2.3 as well as including various fixes and additions. It contains one merchant item table (the "general store" one with things like bags, bread, rusty daggers, torches etc) which all merchants use at the minute.
I'm working on a full set of merchant lists at the minute, the next version should include far more different merchant types.
I changed the name to "world data" since it now includes many other things as well as NPC spawn locations.
