Next release candidate on Unstable

The unstable build has been updated with the next release candidate. This one has taken a bit longer than planned, for a few reasons largely personal, but beyond those I also had to rewrite a very fundamental part of the game - all resource handling. This build is still missing several pieces of art, but is functionally 'locked' for release. The only changes will be bug fixes. As always, no update to the stable branch yet. This is an opt-in beta and will break all saves.

In this update:

• All dwarf clothing / tools is now removable and interchangeable.
  
• You won't find them in the crafting interface just yet, but you can find some color variations on common items of clothing in the god menu.
  
• Tools will break. Different materials will last different times.
  
• Tools do not yet determine how effective a dwarf is at their task, so they are mostly cosmetic. They will happily mine with their bare hands.
  
• Fixed a bug where the teleporter could leave a dwarf in solid rock and kill them.
  
• Large voxel build orders will be composed into a single task in the list.
  
• Zones are designated by a border, not by specific floor voxels - so build them on whatever you want.
  
• Added a couple of new block types.
