Walkaround and more!

I've been tinkering with Sacraments 3D some more lately, and I've made some good progress. The walkaround engine is much more robust and smooth now - you can no longer walk through walls where they come together in an acute angle, and when you go into such a tight corner, it no longer jostles you around as you push into it.

Also, as shown in this screenshot:

...I now have it working with "nudges" (press the space bar to try to open a door or otherwise investigate whatever you're standing in front of) and generating dialog boxes. Yayzers! It actually kinda feels like an RPG, now that you can bump up against things and see text to read.
