Fixed bug where cPlayer's cClientHandle was used after cPlayer was destroyed http://forum.mc-server.org/showthread.php?tid=380

Also removed the SetClientHandle() function from cPlayer
Added a Destroyed() function to cEntity that is called ONLY ONCE after an entity has been 'destroyed'
Cleaned up some code, using enums for GameMode and Weather and replaced some 'const char *' with 'const AString &'
Exposed some more functions to Lua
