P0-B7: Part 1355: Debugging, Improvements

I have been focusing on the games AI for a few days now.

In addition to improvements to the random Creatures, I have also made improvements to the Companion AI.

These were minor, and just fixed an issue with the AI sliding slightly when they stopped on uneven ground.

I have also added some more user-feedback messages to tell them when an item cannot be used or combined, etc. The game currently does not have enough tutorials and help messages, I am working on adding more of these.

The next goal is to continue working on the AI, including the AI within cities and buildings, which is a lot more complex.
