Worldographer Beta tileset added

Well… Worldographer compatible icons are now working.

The way Worldographer handles icons etc is very different than HexKit, and in particular getting the shading effect layers working correctly in Worldographer has been a challenge (if you have previously put together a Worldographer tileset, slide into my DMs!)

This is a beta so please, leave any comments/problems/etc below and we’ll be sure to address them ASAP!
