    * Add pane block type.
    * Add config option to show/hide the generated blocks in the creative tab.
    * Deprecated the material id mapping, it was an overengineered solution to a non-problem. DO NOT remove the config file "config/BuildingBricks/material_ids.nbt", it is needed to convert the worlds.

    * Fix some blocks having a missing textrure in the bottom side.
    * Fix glass blocks not dropping when harvested with silk touch.
