Invoking commit in dialog
Testing button clicks (working at top level, but not in a dialog)
A bunch of tests to find out why button can't be clicked
Testing and button correctly clicks now
Removed all testing
Moved dev test logic into formal test (general_ui_test) and added to ui/all.dart which was added to all.dart
Merge branch 'master' of https://github.com/dart-lang/chromedeveditor into umop-testing-ui-start
Cleaned up and put modal testing into class.
Fixed title -> text & restored broken expectation
Added two kinds of opened dialog checking.  One for functionally open (checks to see if the dialog reports open) and another for visually opened (dialog not visually appearing).  The later has been implemented with a timer.
Reduced time limit to 1 second, added visual test to fist-run test, and fixed broken visibility test
