Gem Storage Blocks

I may be alone here, but I love consolidating my blocks.  Diamonds, gold, iron, redstone, etc.  It also helps me organize how I store everything.  With that thought in mind, I made such blocks for the three gems this mod adds (rubies, sapphires, and peridots).

Most importantly, all of these blocks share a single ID, so we are not introducing a bunch of needless IDs.  In fact, the way I set it up we have room for many more blocks to share this same ID should the desire arise.  @AnarchySage helped me with this a tremendous amount, by referring me to a project where he was doing this himself.

The recipes are what you would expect:  3x3 gems -> 1 block, and 1 block -> 9 gems.

At first I started making the textures from scratch (I have screenshots of the ruby texture I made in-game if anyone wants to see), but I realized it would make more sense to use the existing emerald block texture as a baseline.  So the textures are just color modifications to that, to match the existing gem textures.
