Synthaxe is similar to 'fetch' command with '-i' and '--all' options...
+ Add an option `--with-labels` to the 'fetch' command to get TFS labels when fetching TFS changesets
--AuthorsFile parameter added to the Fetch command and is registered as a singleton.
--Unit tests test the regex of the line parsing.
Updated logic around parsing the original changeset owner. This was needed to properly identify a user who had been deleted from TFS without the need for an AuthorsFile.
