Fix preserve bug causing landmark not to match

Landmarks nested inside a DOM node in a re-rendered range weren't
being preserved, because the selector was being run on the old
DOM and new DOM with the context node from the old DOM.  Fix is to
only use the preservation root 'context' option for the case where
the landmark is above the re-rendered region.
Spark.labelBranch safe on non-element-balanced HTML
all Handlebars helpers drop branch labels
Spark.UNIQUE_LABEL, no matching in bare each
past-tense created/rendered/destroyed

Consensus is that "render" is too confusing a name for what's obviously a callback (after the template is rendered).  We prefer past tense rather than oncreate, onrender, ondestroy.

Wrap all templates in labelBranch with name

This allows multiple helpers with different names to be called from a Template helper with no landmark ambiguity.
