CivianMod

This release largely contains under-the-hood changes, but the biggest user-facing change is the config gui refactor. You may also notice a change in the structure of the config file. This is because of some in-progress features (and some potential features) that defy easy categorisation, so better to do that in the gui than in a serialised data format that is largely abstracted away.

Also:

• The SafeMining threshold has been increase from 1 to 5, and is now configurable.
• ClickDest now only works when you're empty-handed to prevent command spam when breaking a sign.
