Open instrument + event funnel work

* Instrument loader now looks in localStorage for list of instruments
  to activate by default.
* Turned off HTML event injection in favor of extremist view that all
  events should be handled by instruments.
* Load and activate new OpenInstrument by default (added to
  InstrumentRegistry in commit 76cd949).
* Added root to main.
* Added objectOrParentWithProperty to all jQuery objects to return the
  object or first parent who defines a given property.
* Moved loading of jsbridge higher up in html.
