Smelting redstone and lapis ore should give more xp so silk touch is viable

This very simple change doesn't seem much at first but if one thinks about it makes a lot oof sense.

If redstone and lapis ore mined out by silk touch would give more xp when smelted, would fix multiple lategame problems.

This simple change would do the following things:

• Redstone and Lapis would be worth mining lategame
• Silk touch would actually be useful for non-decoration purposes
• Mining quartz wouldn't be the best way of getting xp in the lategame
• Would encurage further mining and exploration
• Wouldn't have stacks upon stacks of never used redstone and lapis
