Memory Management Fix

In recent weeks I've found out there were some memory mismanagement going on in my resource packs, and I just finished the work to fix that. This is more of a "better safe than sorry" fix, as the previous version worked just fine, and it would probably only be an issue in very rare cases. For the Utility pack, I've revamped the documentation, with a table of contents and some small fixed. The pack itself only had the memory optimization, no new features added.

Redownload the pack to get the latest version.

Happy Stencyling!
