Added some form of reference counting to cChunk to make sure it's not referenced when deleting it.
Right now it's only needed due to the generation of chunks in a separate thread and adding it to the spread light list in cWorld

Chunks are now generated before the player is able to see them. This is done because after a chunks is done generating, some blocks might still need to be set (parts of trees from neighboring chunk), causing more bandwidth to be used (each changed block needs to be sent to clients again) and (fps) lagging the clients when changing a lot of blocks. Calculating ahead fixes these issues.
Separated the placing of foliage (trees and stuff) when generated chunks into a new function GenerateFoliage()
Cleaned up the VS2010 project, now using some VS2010 specific functions like dependencies on projects (no need for setting library dependencies manually). VS2010 project now compiles way faster in Release by using multi threading.
