setup.py for bzr-pqm

I've committed the setup.py script with a few changes:
 * changed the name from 'pqm' to 'bzr-pqm' to match the Launchpad product
 * added a MANIFEST.in file so that sdist includes the license
 * include the URL of the product in the package metadata.

In general we want to use python variable names for plugin names. So really it should be either 'bzr_pqm' or 'pqm'.

I think there is a lot of precidence for using 'bzr-foo' for a plugin named 'foo'. as the launchpad project. And IIRC launchpad doesn't let you use underscores in project names. So we have a fundamental incompatibility between launchpad names and plugins that want to use valid python names.

However, since you only changed the project name to bzr-pqm, but left the installed path as 'pqm', the change seems fine.

I guess I wasn't quite clear. I left the Python package name as "bzrlib.plugins.pqm".

What I changed was was the name used in the tarball. With Etienne's version, "python setup.py sdist" would generate a tarball called "pqm-$VERSION.tar.gz". I changed it to use "bzr-pqm-$VERSION.tar.gz".

I used synaptic Package manager. I type in the search box pqm an got bzr-pqm I tick the box to install is the 0.12-2ubuntu1 is this a good start to work with.
