Add handleRangeChange support to addRangeAtPathChangeListener
Update FRB to v0.1.19

This includes some changes to the FRB syntax that impact repetition and
content controller.  Particularly, .* notation has been removed and
bracket[key] notation has been repurposed for properties instead of map
content.

I also moved the serialization bindings module into
core/serialization/bindings.

I also removed the old selector property language spec.  It is replaced
with FRB.
Merge montagejs/integrate-bindings into kriskowal/integrate-bindings
