Fixing problems introduced by the model change.

* Many calls to ``ts_ext_data:get_properties/1`` from ``ts_api`` were passing
  the record reference, not the record itself. Fixed.
* Created ``ts_api:put_user/2`` which updates a ``ts_user`` record. This is
  needed specifically for updating the ``liat_timeline`` extended data property.
* Removed unreachable code in ``ts_api:post_entry/3``
* Fixed return value of some ``ts_user`` functions to use the
  ``{Status, Value}`` convention. TODO: make sure all calls are using the same
  convention.
* Fixed error message formatting in ``ts_ext_data:set_property/3``.
* Added clauses to ``ts_json:ejson_to_record/2``,
  ``ts_json:ejson_to_record_strict/2`` and ``ts_json:construct_record/3`` to
  handle the ``ts_user`` record type.
* Added code to ``AppView.loadInitialData`` and ``AppView.selectTimeline`` to
  support the ``last_timeline`` extended data property.
