minecraft:copper_block name is inconsistent with other mineral block names

The name of the block is "Copper Block", which is inconsistent with all other mineral block names (besides "Lapis Lazuli Block"). I'm not sure whether this was an oversight.

Solutions:

• Rename Copper Block to Block of Copper (and optionally Lapis Lazuli Block to Block of Lapis Lazuli)
• Rename all other mineral blocks to "materialtype Block" - would help them to fit in better with their namespaced IDs as well as other English translations
