Procedural world generation - ground and traps seems to not generating.

[Darkhog]

OMG! Found issue. I was using byte for array of TChunk and AIRID was defined by -1. Me and my stupidity... Now it works nicely.

//edit: When I set chunk x/y when generating world to other number than 0, it generates same exact chunk no matter what I do .

//edit #2: This is most current version of my world generation class: http://pastebin.com/sPsfNWLD. I've applied optimization fixes suggested by User137 and SilverWarrior, but it is moot point since it generates exact same chunk no matter of what value I put into chunk x/y.
