- Rebased #5006 upoon master and created #5281 from #5006
  - Setup regression test based on client provided input
  - Fixed bug with multiple spurious directory occurances

   Implementing allowed vs foreign line lookup for the zip service

   - Adapting `lib/stif/netex_file.rb` to expose the already implemented matching
   - `app/services/zip_service.rb` augmented to check for allowed lines and returning forbidden lines
   - Specs with fixtures and using the beforementioned new zip support in the specs
   - Fixture directories for the new specs

   Zip Support for Specs, allowing to create zip archives in memory

   * create zip archive from hash or directory tree
   * Metaspecs -- commented out
     - for potential refactoring of Zip Support
     - as readable documentation on how to use Zip Support

Speced and implemented ZipService to return additional directories
in the entry's `spurious` field.

These relied on the previous behaviour of `#post_resource` handling
uploads. This is no longer the case. Instead, you have to call
`HTTPService.upload` manually and pass the result to `#post_resource`
via the `params` argument (like in `WorkbenchImportWorker#params`).

This is no longer being used as the `WorkbenchImportWorker` was
refactored and it was decided that we don't want to enable retries for
imports.

For example, imagine you have an hour-long import that fails after 50
minutes. We retry three times and now we've wasted 2.5 hours of your
time just to tell you that the import failed.

Thus the decision was to remove it.

        - Replzed Lazy Enum over get_next_entry and group by with explicit looping and yielding to an instance level enumerator
          that yields streams per subdir (wich represents a referential).

        - Fixtures and Specs that use a REAL usecase.

        Next: Get rid of metadata kludge (should fix failing specs)
