Fix BLOCK_ID deprecation

- All Changes
  - Modified BlockData to use BLOCK_NAME, which stores blocks by name. Requires database remake.
  - Modified all insert methods to use BLOCK_NAME
  - Removed all BLOCK_ID methods. We don't like that.
  - Remove some debugging/test messages.
- Notes
  - When bukkit provides us with a method to use block data vals (trees etc), I will fix the deprecation issues with that.
