Suggestion: Remove baz importers from bzrtools

[Kevin Smith]

I think the idea of splitting up bzrtools has been discussed before. I
would like to propose a less drastic version: Remove the baz importers
from bzrtools.

First, the number of people migrating to bzr from baz has to be a tiny
fraction of all the people using (or planning to use) bzrtools.

Second, importing would typically be done once per project, and never
again.

Every time I do bzr help commands, I am annoyed at having to ignore two
commands, near the top of the list, that I will never use.

It's a small thing, but many small things add up to a significant effect
in the overall experience of a tool.

Thanks,

Kevin
