Added (Important): Checks for proper custom texture registration and handling. This means if you are using Optifine and have been getting missing textures bug, the game will crash (at least until Optifine fixes their incorrect handling of custom textures). If you want to use optifine, you'll have to remove blocks with custom textures.

Added: Localization support (currently limited English, German, Chinese and Pirate)
Added: Automatic NEI Documentation support (so other mods can automatically tie into it - see the localization github for details)
Added: Transfer pipes can be wrenched to have no outgoing directions
Added: Cursed Earth mobs will despawn after 3 minutes.
Added: Cursed Earth placed underneath a vanilla mob spawner will cause the mob spawner to periodically spawn mobs even if no players are nearby (these also despawn after 3 minutes)
Added: Shift-click support for Item Filters.
Added: Shift-click support for upgrades in transfer nodes
Added: FMP Glass blocks are now auto-scaled to fit their block size. (Slightly buggy on hollow covers but this is unavoidable)
