Vertical Slabs Everywhere

Vertical Slabs Everywhere 1.21.1-1.0.1

Bug fixes:

• Slab naming now matches Quark's convention (e.g. "Oak Vertical Slab" instead of "Vertical Oak Slab")
• Fixed vertical slabs not generating for Vanilla Backport blocks (cinnabar, polished cinnabar, cinnabar brick, sulfur, polished sulfur, sulfur brick, resin brick) and other mods using the minecraft: namespace trick

Improvements:

• force_generate config option is now a full override, generating a slab even if it would normally be skipped by skipped_mods, skipped_blocks, or the vanilla/Quark duplicate check
