Expanded protractor tests and made sure that midi inputs can be enabled and disabled correctly.
- Added a way to view unite tests in chrome.
- Upgraded legato to 0.2.6
- Moved protractor selectors and test functionality into page objects.
- Added the ability to update message middleware midi inputs so that OSC outputs aren't lost when midi inputs change their hosts.
- Legato mock now blocks midi messages from midi inputs that have been disabled.
