* Resolved D0020: Add exclusion filter for entries.
* Refactored ``timeline`` fields of several objects in ``ts.js`` to be
``timelineModel`` to be explicit.
* Added support for exclusions in ``EntryListView.renderOne`` and
``EntryListView.render``.
* 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.
* Transformed the test database to match the new data model. Added
``ts_ext_data`` table and moved ``ts_user.ext_data`` values to it.
* Added D0022: cascade delete ``ts_ext_data`` when ``ts_entry`` record is
deleted.
* Completed refactor of ``ts_api`` functions to account for extended data:
* ``post_entry/3``
* ``put_entry/3``
* Created ``ts_entry:write/2`` to write extended data atomically with the entry.
* Fixed copy/paste bug in ``ts_ext_data:create_table/1``.
* Fixed implementation of ``ts_ext_data:set_property/3`` to be explicit about
taking a record, not a reference. It then extracts the reference and passes it
to the underlying implementation in ``ts_ext_data:do_set_property/3``.
* Refactored ``ts_ext_data:do_set_property/3`` to take a record *reference*, not
the record itself.
* Refactored the ``ts_ext_data:get_property/2`` and
``ts_ext_data:get_properties/1`` functions to return key value tuple pairs,
not ``ts_ext_data{}`` records.
