Patch 1.5.22

• Fixed things.
• [MC 1.8.8/9] Fixed metadata computation of some rotatable blocks (e.g. screens, keyboards), leading to funky effects (them turning into blocks from other mods typically).

Updated 2016-02-07: Hotfix for new GC sandboxing breaking old OpenOS installations (and potentially other scripts). Please re-download. Terribly sorry about this!
