dpp_issue_588

LazyLoading had a number of issues.  It would not support multiple lazy loads on a page, the execution of the lazy snippets was serial, the wrong render version was posted for the functions created.

I fixed some underlying issues with thread pooling (the thread pools grow and shrink and the thread pools used for ActorPing support multiple threads.

I created a generic method on LiftSession that will capture state for deferred processing.

I updated the lazy loading and parallel snippet code to use the deferred processing code.

I added an attribute to lazy loading to allow the embedding of a template and if the attribute isn't specified, the spinning loader image is used by default.

I created examples of both lazy loading and parallel snippets in example.

Smoke testing against example code.
