deprecation warnings about debian_bundle

[Martin Pool]

It seems like this must already be a dupe, but on maverick we get a lot of

/home/mbp/.bazaar/plugins/builddeb/tests/blackbox/test_mark_uploaded.py:21: DeprecationWarning: please use 'debian' instead of 'debian_bundle'

Will just a simple search and replace do, or do these perhaps need to be conditionally guarded to keep builddeb working on older releases?

[Martin Pool (mbp)]

I see there are already some guards like this:

try:
    from debian.changelog import Changelog, Version
except ImportError:
    # Prior to 0.1.15 the debian module was called debian_bundle
    from debian_bundle.changelog import Changelog, Version

so I'll just add some more.
