Material Counter

Fixed major issues:
- The entire first page of the Required Materials book was incorrectly bolded instead of only the header.
- The Required Materials book no longer cuts off block names or values when there is too much text on a page.
- The datapack now counts only water source blocks instead of all water levels.
- The datapack now counts only lava source blocks instead of all lava levels.
- The datapack no longer counts portal blocks: Nether Portal, End Portal, and End Gateway.
