Description

Currently there are a number of anonymous inner classes that are used for implementing state change listeners for configured objects. Most of these do not need to implement every method of the listener interface. As a result we have many lasses with many empty method definitions.

To reduce the code size we can have all the anonymous classes extend from an abstract base class which provides empty implementations
