Crafting Guide Fixes

After someone sent me a small fix for the new crafting guide (thanks, Soas!), I decided to check over every level requirement and experience value to make sure it was correct. In other words, I completely revised all of the values for the Jewelry section and fixed a great deal of errors. What had happened was, I used the old crafting info from RuneScape Classic, thinking that the values would be the same. They were not, and I apologize for making an incorrect guide.
