games/gog: Add War for the Overworld
This was the whole reason why I implemented the monogame-patcher even though it is very useful for other games as well. So the main issue why patching was needed is that the game writes its savegames into the same directories as other assets, so we need to be very careful about which method we patch and how in order to avoid failures to load other assets rather than savegames. However while in principle the game runs fine there is a Heisenbug hidden, so it segfaults whenever strace is not used. Here is the backtrace: #0 0x0000000000f973be in ??

Probably the reason why it works with strace might be a race condition, but I haven't thoroughly debugged this. Especially if there are no symbols available it's very hard to debug, so I'll leave that to some day in the future. Signed-off-by: aszlig <aszlig@nix.build>
