Fixed ignoring of subpaths inside a repository

[not-implemented]

Use-Case: Explicitly matching a subpath inside a repository for ignore or moving to another repository like that:

# ...
match /trunk/project/bigdir/
  action ignore
end match
match /trunk/project/
  repository trunk/project.git
  branch master
end match
# ...

Problem: When there is a change to /trunk/project/ (e.g. changing a property), recursiveDumpDir always dumped the complete subpath to the parent repo, ignoring the rules of subpaths.

This pull request implements rule matching also for recursiveDumpDir.

Sorry for "error: ‘ruledebug’ was not declared in this scope" ... I'll fix it tomorrow

Fixed now.
