Removed filtering of message that is no longer produced.
Changed the behaviour when mutating a configuration whose child has been resolved from an error to a deprecation. This will become an error in Gradle 3.0
Reworked mutation checking in DefaultConfiguration to warn about any change that may affect a child configuration, and to include the configuration that is  being changed in the warning, rather than the configuration that was resolved.
Added deprecation to release notes
Added some more int test coverage for mutation of configurations after resolution
