Slopes update cleared of image files that were bloating the mod size. Whoops!

Slopes update pushed

Fixed unfinished UV mapping in the "Half Slope Base" block's buildstates.

[Prior updates are empty pushes or a thumbnail change.]

This update adds a much-requested suite of 8 half block shapes, a new "Brace"
block, tweaks the 5x5x5 Frame block's design, Increases component count/durability,
fixes some UV errors, and adds Mod.io support (tentatively).
