DFHack 50.09-r3rc2

The Windows build attached to the DF beta branch (build 11941433) is a mixture of 50.09 and a few unspecified low-level changes. There are no new features for players to use, but the internal structure differences make this particular version difficult to support at the same time as other, more popular builds (i.e. the default Windows 50.09 build and the beta Linux 50.09 build).

This update just removes support for the Windows version in the DF beta branch. The Linux version in the DF beta branch is still supported, and we still encourage Linux players to switch to the DF beta to try it. Windows players should stay on the default public DF branch for now (regardless of whether they use DFHack).

Also there's a small update to autobutcher that protects animals that you have marked for war or hunt training from butchering. Before, if you had marked an animal for war/hunt training, but it hadn't been trained yet, then autobutcher considered it available for slaughtering.
