Reversed log output

[Chris Lee]

I implemented a patch based on Sebastien Cote's work to implement
reversed log output, matching what subversion and CVS do by default.

It's available at http://c133.org/tmp/bzr-rlog.patch - it adds a new
command - 'rlog' - and does not change the existing behavior of
the 'log' command.

Should work fine on both python 2.3 and python 2.4. I was tempted to
make use of 'reversed()' but it didn't really help much and it's
2.4-specific so this patch doesn't use it.
