Merge lp:~jelmer/brz/setuptools into lp:brz/3.0

[Jelmer Vernooij]

Use setuptools in setup.py.

Use setuptools in setup.py.

This allows various new options for setup() to be used, such as
install_requires. setuptools is already common enough that this should be fine.

[Martin Packman (gz)]

Launchpad doesn't like the branch, but looked at the changes and all seems reasonable. Is possible we want to update some of the other bits (like using pkg_resources for version parsing) but that can be later.
