keep jshint happy
don't plot message until get obj back from blip; fix enter()/exit() selection tracking
add TODO to Watson re: removing references to utcTime
add addDatum method for use in message creation; add some tests
move message click handler so that don't need to wait for navigation-triggered rerender to be able to click new message
on message creation, update tideline's data and emit event for message.js to catch and plot new message
remove the assumption that nothing coming into Watson has a normalTime (messages do, now)
