Better Slabs Mod

- revamped the version checker

-- now notifies you if your mod version is ancient, old, or somehow from the future, I don't know how

- added messages on world join

-- sends you a personalized message by me

-- also sends you a link to this post to download the latest version if you're running an old one.

- implemented axis modes

-- similar to placement modes

-- allows easier placements for blocks like logs (and pillars in the future)

- tweaked key bindings

-- F9 circles around placement modes

-- F10 circles around axis modes

- added all types of woods and their corresponding leaves

-- GLITCH: Some logs have weird stretched textures

-- GLITCH: All leaves have different color applied and don't work with FAST graphics

- added all colored blocks

-- prepared the code for 1.12

- internal optimizations

- WIP feature (disabled) - GHOST BLOCKS

-- a see-through slab of all mod's slabs are visible when about to be placed (helps you place them)
