* Re-implement Synthetic Dirt and Synthetic Sand, changed their textures and and unmarked them for renewal.
* Added new Composite Block which serves as a crafting ingredient for the Labyrinth block and other decorative blocks.
* Changed Composite Food to use it's own texture and buffed it's saturation values.
* Made Composite Glass Pane top texture transparent so it looks better in-game now.
* Fix Observation Glass Pane item texture. (Block texture still broken, no idea how to fix right now)
* Preparation for new blocks to be added in the future.
