[MERGE] test-progress-bars

[Robert Collins]

http://people.ubuntu.com/~robertc/baz2.0/test-pb has an updated, and now
working correctly, selftest using progress bars.

Diff attached against .dev.

The output looks like:
--------------------
 ./bzr selftest

----------------------------------------------------------------------
Ran 2321 tests in 308.639s

OK
------------------

The multiple lines are due to 'test stipple' - output being generated by
comments output to stdout during the test suite. We shouldn't have any
of this, so its a good prompt to fix them.

selftest -v operates unaltered with this patch, so when you care for
checking specific tests you can still do that.

What do you all think? I find this much nicer than no output or dots,
because it marks how far the progress has to go.
