   File Filter - Regular Expression maching filter
   
   This implements an ordered include/exclude filter list that can be used
   to filter filenames.

   Pattern matching is done identically to rsync, the key points are:
    - Patterns containing / are matched against the whole path, otherwise
      only the file name is used.
    - Patterns that end in a / only match directories
    - Wildcards supported by fnmatch (?*[)
