Updates the platform shims in dev/manual_tests so that Windows and Linux can be built. I had to update the Windows shims, because I was unable to build a Windows app there.

Also updates the analyze.dart script to report all license issues simultaneously instead of just dying after the first failure.

The only substantive code changes are in dev/bots/analyze.dart and dev/bots/test/analyze_test.dart

New parameter for InteractiveViewer: scaleFactor, which allows control over the speed of zooming.
