PHPMD rules for SilverStripe

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
