Adds NON_BROWSER & DEFAULT match flags

This change adds two new flags for starting activities:
FLAG_ACTIVITY_REQUIRE_NON_BROWSER and FLAG_ACTIVITY_REQUIRE_DEFAULT.
The first will only start if the result is a non-browser result. The
second will only start if the result is not the resolver activity.
