Bhaptics

Added partial bhaptics support for the game. If you have the suit and it's not working properly or you would like to see something new added, let me know. The support is only partial, for the vest and the face haptics, but it provides a nice framework on which to build further support. 

For those that don't have bhaptics, this update brings a new sky design which looks a lot better. Especially the sunsets.

Other than that I also improved the ai system but most of that works in the background so there shouldn't be any changes in functionality. 

For next week I'll continue working on some new features I had planned, like sleeping/camping. I doubt I can finish both on time but I'll do my best.
