In version 0.9.14 the getNext() method has been removed, but the FilterAttachable interface still only contains the method getFirstFilter(). This leads to the situation that for an appender only the first filter can be traversed by application code.
I need to be able to access to full list to provide some visualization of the current working logging configuration.

I raised this as a "blocker" since this prevents me migrating from 0.9.13 to 0.9.14.
