BUG: foamCleanPath problem if path contains @ (closes #264)

- Can occur with some user names, or mounted paths.
  Resolve by using '?' for the separation character.

  Since '?' is a shell-glob, it is highly unlikely to occur appear in
  filenames.  Additionally, it is not a meta-character in standard sed,
  nor in the GNU extension (which uses '\?').
