- Added new directory (/svn-logos) to svn -> p4 mapping for collab.net's svn
  code tree.

- Improved handling of svn "A" and "R" actions: Threat those consistently as
  p4 "integrate/edit" during the conversion.

- Improved handling of remote svn repository disconnect: Try re-connecting on
  the 'Service Unavailable' error.
