Update for Tile Support to eliminate tile offset from enum additions

tile_config_template.json is an accurate template for all items and hardcoded tiles as of 2 Sept 2013 at 8:00pm CST

tile_id_data.h updated hardcoded keys to include added enum values.

Added comments to the top of enums referenced by tile_id_data.h's arrays to hopefully reduce the need to do fixes like this in the future.
