gems + gem nodes + encrustable tools (from moreores, default)

+gems
+
+Adds five gems which can be encrusted into your tools. Currently supports
+moreores and default tools.
+
+Added gems, from worst to best: garnet, aquamarine, topaz, diamond, opal.
+
+Gems are encrusted by placing the gem and the tool into the crafting space.
+A garnet-encrusted mese pick is worse than a topaz-encrusted gold pick.
+
+A aquamarine-encrusted mithral axe is 10% faster and lasts 10% longer than a
+normal mithral axe.
+
+Steel, gold, and mithral are the only encrustable tools. Mese cannot benefit
+from the effects of gems because it lacks the magical attunement to be
+encrusted (or, in other words, balance).
+

+garnet		5%
