Better caching for document textures and information

Browse Source 
Move thumbnail creation into ShellTextureCache.  It's now asynchronous,
and we cache the result.

Create a DocManager class which keeps around the DocInfo objects between
invocations.  This is also where we ensure we remove thumbnails for
recent items not known anymore.
