Block textures

I "finished" basic textures for the dust storage blocks, although I feel the infused ones could benefit from "carved" details, perhaps like chiseled sandstone if that makes sense with the crafting mechanic...

On things making sense, I was thinking about how to convert the infused blocks into usable pieces; I fell it makes sense to craft the inert block with 4 dust pieces, but the infused blocks should give 9 "usable" pieces, although plainly crafting them into an infused version of the inert dust pieces would be silly, as they are crafted with 4. perhaps making them into "chalk" of some kind would work, as it would be nice to be able to draw on any side of a block.

Anyways, no need to merge this just yet (unless you really want the textures now, of course), I would like to finish up the textures for the usable items (when I know what it should be) and making a new pull request every two days seems annoying :p
