dgetlp doesn't work with dscs offered by launchpad

launchpadlibrarian.net is HTTP, and dget will handle the newer https://launchpad.net/ubuntu/<release>/+source/<source>/<version>/+files/<file> links just fine.

However I'll fix the error message so that it shows that it only works for HTTP.

ubuntu-dev-tools (0.60) jaunty; urgency=low

  [ Jonathan Davies ]
  * ubuntutools/common.py: Now split into multiple files depending on
    function.
  * Adjusted imports on all files as necessary for the change above.
  * Removed ubuntutools/misc.py's mkdir function - superseded by
    os.makedirs().
  * dgetlp: Improved error message to show that dgetlp only accepts HTTP
    URLs (LP: #322051).

  [ Iain Lane ]
  * requestsync: Only attempt to change bug importance if in ubuntu-dev, as it
    will fail otherwise (LP: #320984).
  * ubuntutools/lp/functions.py: Rename urlopener import as it conflicts with
    a variable, causing an error.

  [ Luca Falavigna ]
  * pull-debian-source: do not fail if package name contains a hypen.
  * buildd: display help message if no parameters are passed.
