Make ActionUIVerifier Xcode friendly with proper warning and error messages

Xcode needs to see the proper prefixes for warning and error:
"warning: not great but we will live"
"error: bad situation"
Add ActionUIVerifier as a dependency for ActionUISwiftTestApp and run the verification when building. This will catch mistakes and also is a demonstration of the best practice in production environment.
Turned off Xcode user script sandboxing because it does not let specify a directory with GLOB content for the source declaration.
