Basically, modal windows had their own thread-locking for what drawing was possible. This is a bit nonsense now we have a game-thread. And it makes much more sense to do things like NewGRFScan and GenerateWorld in the game-thread, and not in a thread next to the game-thread. This commit changes that: it removes the threads for NewGRFScan and GenerateWorld, and just runs the code in the game-thread. On regular intervals it allows the draw-thread to do a tick, which gives a much smoother look and feel. It does slow down NewGRFScan and GenerateWorld ever so slightly as it spends more time on drawing. But the slowdown is not measureable on my machines (with 700+ NewGRFs / 4kx4k map and a Debug build). Running without a game-thread means NewGRFScan and GenerateWorld are now blocking.
