Re-add GregTech unstitch (d221f038a4ea4f67ef0c55e9bcc5da97e1d5c664) with correct path. There are several blank textures that require fixes.
Updated GregTech dusts, ingots, plates, metal blocks and tools.
Copied GregTech stone ore textures over to core ore texures. Definitely not full coverage.
Updated most GregTech machines to v3.11. Added animations where required.
Ported IC2 uranium ingot, personal blocks, and boats from JSTR 1.6.
Updated Invar block.
