New Avatar Core minor release coming soon

I've made some changes and improvements to the Avatar Core framework. There are some bug fixes, some API changes, and most notably, the ability to easily create copies of most objects via clone methods. Before, you could do this by writing and reading XML, but this way is a little easier. I'll have to update all the documentation, demos and samples to make sure they'll still work with the changes, then I'll post the update to the project page.
