Patch 1.0.0.9 - A few fixes and a few less crashes!

This patch does the following:
- Gets rid a crash related to trading.
- Gets rid another crash related to drinking milk.
- When dismantling damaged drawbridges, the hp-bar will disappear as well.
- When wall banners placed on the outside of buildings will become transparent when view indoors.

Best wishes and lots of love! //Mattias
