Minechem 5.0.5 RC4

This RC is mostly minor tweaks, like fixing an incorrect chemical cost, and making gem dusts not get their recipes overridden.

Minechem v5.0.5, release candidate 2

What's a release candidate? It's a build that we're 99% sure is ready to be considered an official release. If no major bugs get reported in the next week (please report all bugs on the Minechem issue tracker!), we'll stick a fork in it and call it "done!".

As always, make backups, but this version should be safe for use in any and all production servers.
