Windows threading fixes

Further cripple Deci2Listener pending Windows implementation, finish converting POSIX threads to std::thread. Hardcoded pathing in overlord\fake_iso.cpp until environment variables can be implemented for Windows.

Currently loads KERNEL.CGO and links gcommon object file, but crashes when executing due to Windows/Linux differences.
