1.0.0

Initial release.

Content

• Added the Keyboard, a fully working second instrument for Groovy: 6 chords (major 9 down to minor 9♭5), a piano voicing, its own held-in-hand model and inventory icon, and its own two-armed playing animation.
• Craftable from 3 gold ingots, 5 planks, and a note block.
• Shows up next to the Guitar in the creative menu and JEI.
• Included the original Blockbench source files (the held model project and the animation project) so the Keyboard's look and pose can be reopened and reworked directly, as an example for any pack developers.
• Added a README with a full file-by-file breakdown of the pack and a step-by-step guide to turning it into your own instrument.
