Code review comment for lp:~jameinel/bzr-builddeb/import-scripts-updates2

This adds some small tweaking to the import_package.py script. Probably needs some direct comments about what we should keep, but it was useful for me when trying to get started and debug what was going on.

      Several small updates.
      1) handle when madison-lite is not installed more gracefully
      2) enable_default_logging() before loading plugins, in case something fails to load.
      3) allow passing -Dxxx flags for bzrlib to use for debugging (like -Dhttp, -Derror, and -Dhpss)

This is currently committed on top of import-scripts-updates, but I can pull them back apart, there isn't a code-level dependency.
