--User changes

-Add toolbar buttons to switch some rendering options without having to open the options dialog.

--Bug fixes
 -Only update summary on render completion, no need to constantly update it.
 -Properly handle cancel even on variations dialog.

--Code changes
 -Add small function ShutdownAndRecreateFromOptions() to wrap shutting down the timer and recreating the renderer.
 -Use the overridden accept() and reject() functions more consistently across dialogs.
