Patch 0.8.4.6 - A few improvements (mainly fire fighting)

This little patch does the following:

• Improves fire fighting. Units will more easily detect nearby fires and once a fire is put out they will find the next one better.
• Fixes a bug where a dead unit stuck behind a tile would get caught in a fall-unstuck-fall loop.
• When loading a game, floating carts should be fixed and find ground beneath them.

Best wishes and lots of love! <3 //Mattias

EDIT: Patched the game again under this version - I fixed an issue where visitors would arrive and then instantly leave for no reason.
