Separation of module filters and traversing a publish tree for copy / rm / mkdir / etc

The current code in charge of traversing a module tree or its delta for publish suffers from many problems:

1) The class name is vague and not informative (PublishCopyUtil)
2) It suffers from an inconsistant api (was designed stateless, became stateful, but not fully converted)
3) It suffers from overlapping concerns (filtering and determining if module requires restart are intertwined in this logic)

These systems need to be broken apart. The scope of this jira is to create new runners (for incremental or full publish) without reference to IModulePathFilter, and to enhance the interface for IModulePathFilter to be able to provide clean deltas.

Test cases for all should be provided.
