Add spectron testing capability

[jwir3]

There is a the capability to run end-to-end tests using spectron in electron-boilerplate. One difficulty we have, though, is that the google login prompt is shown first. We should be able to have basic functionality without displaying this prompt.

The tasks for this ticket include:

• [ ] Enable spectron end-to-end tests within Arbitrator package.
• [ ] Extract out the google login functionality so that only the tasks that depend on the google apis are blocked by the user logging in (e.g the display of the menu and text box should not require a google login, but the display of the calendar dropdown _should__).
• [ ] Make the end-to-end tests check for an arbitrator window, the title 'arbitrator', the menu bar having title 'arbitrator', and the text box existing.
• [ ] Make the end-to-end tests run on travis
