Changes

- The GUIs have been FULLY rewritten utilizing a new library to help support 1.8.8 again. Please let me know if you have any issues.
- If you are using a material in any of the GUIs that are known to have issues working across all versions of MC, they will now be replaced with a barrier to ensure the GUIs will still open.
- If you are using a material that's known to be problematic in supporting cross-version support, it will now default to a barrier block so that the GUIs will not break and still continue to open
