Overall, I think 'bzr switch' should be moved into core, and it should be
updated to not fail if the current target cannot be reached.

I had started down the road of using relative paths, but it has only been done
for 'parent'. The #1 reason is just that nobody cared to do the work. The #2
reason is that it should really have a new format, since older clients will
fail when trying to access a checkout using a relative path. #3 is that the
relative path code should probably be a bit smarter. If I'm using:
/home/jameinel/test/bar
and
/srv/bzr/bar

Having the checkout path be:
../../../../srv/bzr/bar

Isn't very helpful (and is rather ugly). So the relative path code should be
aware if it is going through '/', so it knows to just use an absolute path.

If you want to work on it, though. I would recommend getting 'bzr switch' as a
core bzr command, rather than just being part of bzrtools.
