Extended mess detection rules from phpmd for SilverStripe applications. The rules make it easier for developers to comply with the SilverStripe Coding Conventions. It uses mostly standard PHPMD rules, with a few notable changes:

• Replaced UnusedPrivateField with UnusedInstancePrivateField rule, to check to instance fields only. Unused private statics are by design in SilverStripe.
• Replaced CamelCasePropertyName with CamelCaseInstancePropertyName rule. Static properties in SilverStripe are snake cased.
• Removed inflexible checks around camelCase naming conventions
