v1.2 - Release Compatibility

So! Ol' T.C.'s D.D. is through with its R.C.s and is a real M.V.P. Or something. Anyway, did you hear that Dicey Dungeons came out this week? It's a real honkin' good time. It's also a black hole of productive hours, like the ones you would otherwise spend updating your mod. Having wrangled one or two of those hours from the dungeons' vicegrip, I can now say that Floorplan is fully compatible with Dicey Dungeons' release version. Hoo-rah-ray.

(It was pretty much fine before, the room system hasn't changed since the alpha, but there were some little stylistic things that warranted adjustment.)
