This new build 0.11 includes a rewrite of the FPS AI code, plus a couple of other fixes in the 3D levels.

Streamlined the AI code and ironed out a few issues with their navigation, so the 3D levels are nice and solid.

Also fixed an issue with sorting on plants in the main town.

Last thing - a small change but fixes something folks were getting stuck on - I have changed the conversation with Ernest (the guy who gives the salt) so you no longer need to keep prompting him to continue the conversation (and ultimately getting the salt). The conversation now continues automatically.
