Changes iterateXMLChildren to iterate over just the element children, thus the name change.
Updates test data to be homogenous.
Adds a global render/rendered function to return special tinytlf render/rendered Event instances.
Several framework updates to better synchronize rendering and updates. Not finished yet.
Virtualization done -- pretty inefficient though. Need to restructure some things around and emit visible nodes differently to finish it. Framework pretty messy too, will clean up in a few commits.
