[JuiceyBeans]

What

• Update stripped rubber wood texture
• Update treated wood sign texture
• Added GUI textures for hanging signs located in gui/hanging_signs (will not work until we have our own HangingSign BE)
• Fix sides for battery blocks
• Fix CTM for light gray lamp
• Fix animation frames for data stick, wetware mainframe processor
• Remove a bunch of unused textures and mcmetas
• Move some textures into block/misc for better categorizing
• Rename block/cover/OVERLAY_SCREEN.png -> block/cover/overlay_screen.png

Implementation Details

Changes battery block texture paths in model definition to point to correct textures (should not affect texture packs)

BREAKING CHANGES FOR RESOURCE PACKS BELOW

Textures moved: block/industrial_tnt_side -> block/misc/industrial_tnt_side block/gearbox -> block/machines/gearbox block/cover/OVERLAY_SCREEN.png -> block/cover/overlay_screen.png

Outcome

Fixes #1971 Additionally, MC should complain less in the console about broken paths
