Better Statistics Screen

As always, if for whatever reason you have TCDCommons installed alongside this mod (even tho. you don't have to), make sure you update it first (unless you want crashes).

• The UI buttons featured on the BSS page now use the Vanilla Minecraft button rendering method. This is more texture-pack friendly.
• Added a stat grouping filter. It lets you define how stats are grouped.
• Added a stat sorting filter. It lets you define the order in which stats are shown in each group.
