(svn r12538) [NoAI] -Codechange: introducing fiber.hpp, a class to have fibers in your application via either Windows Fibers, or via thread.h
[NoAI] -Codechange: rewritten ai_threads.cpp, to work with Fiber class. Reduces code duplication, and should fix all the stupid asserts we had with newgames and dying AIs
-NOTE: now my head spins.. 24 hours of working with threads/fibers is bad for health :p Tnx glx for the testing!
