IE sheetmetal vertical slabs are inconsistently named

[saltyseadoggo]

This mod's vertical slabs for Immersive Engineering's sheetmetal blocks are inconsistently named with IE's blocks:

• The metal name/color should come before the word sheetmetal; Copper Sheetmetal Vertical Slab instead of Sheetmetal Copper Vertical Slab
• The word colored should not be present in the names of the colored vertical slabs; White Sheetmetal Vertical Slab instead of Sheetmetal Colored White Vertical Slab
