stonesense crashes after unload/reload

[ab9rf]

If one closes stonesense, unloads the stonesense plugin, reloads it (with or without rebuild), and reopens stonesense, stonesense crashes

does this still happen after the cleanup? I've been able to reload the plugin and run it successfully on Linux

Still crashes on Windows, while trying to display the splash image. Interestingly, on reload the plugin does not attempt to reload the splash image; it uses the bitmap that was "previously loaded".

My guess is that Allegro doesn't properly release GDI, GPU, or DirectX resources, which prevents the DLL from unloading, and so the call to FreeLibrary doesn't actually free the library, so when it's reloaded DllMain is not called again to reinitialize global statics, leaving the plugin in an inconsistent state.
