first pass on repeats.

- refactoring of schemaformbuilder to remove unnecessary methods/cleanup and modifications to get it to emit triggers that i need for insert at the top and insert after
- implementation of ajax server side method for setting the repeat index and support for capturing and sending back event responses for all server requests.
- implementation of client side repeat support: dom manipulation of repeat elements, identifying and relating widgets with model data, creating prototype clones, and support for some XFormsEvent (chiba-index-changed, chiba-item-inserted, chiba-prototype-cloned, chiba-id-generated)
- changing background-colour to background-color in the dashlet.  funny.
- handling a null pointer exception in the errorbean when an error is thrown from the ajax stuff.
- minor debugging enhancements in TemplatingService
