Title: better messaging for windows pub

Better messaging for the pub/windows issue. This gives the user an indication that Dart projects will be broken on windows until they take action, and tells the user what action to take. fixed https://github.com/dart-lang/chromedeveditor/issues/2991

- when auto-running pub for new project creating, display a dialog telling the user they need to install the dart command-line tools and and to manually run pub
- tweak to an error message for a launch failure
- fix an analysis warning in grind.dart
