Forking baazar to add Python 3.x support

i also don't see why its a bad thing, since lets consider the platforms
that bazaar runs on:
linux: simplest of the bunch, since linux users will use their package
manager to install bazaar, which will pull in any needed deps, like python
3. Not to mention that many distros like ubuntu already ship python3
installed by default
windows: we install a python installation anyway, so it doesn't matter what
version of python bazaar uses
mac: sort of in between linux and windows, it has an installer which i
guess could install python 3 if its not already installed.
Not to mention that python3 is the 'future' of python, i think 2.7 is the
last python 2 major release?
