Added WearableItem class to the framework. This class can be used to: load from disk, create from code, or modify a existing Wearable item. Its not currently used by anything in trunk but is a handy utility class.
I'll be writing some instructions on its use as part of a more general article on various methods of creating better initial avatars for new users. Which will include some code samples, but as each grid has its own requirements, there will be no out of the box solution included.
