StoneWork Factory easier selection on block to generate

[NielsPilgaard]

Enigmatica 6 has added a ton of new blocks that the Material StoneWork Factory can create. It takes a while to click through them all, and it's easy to go past the one you were after.

It would be helpful if right-click showed the previous block, and left click the next, so going past the right one wouldn't matter as much.
It would also be helpful to be able to use the scroll wheel to select them.
Having them selectable in a drop down would also be a good option imo.
