0.6dev: Complete rework of the slave-only install to use `setuptools.Feature` to disable the master-parts. This should make all regular distribution commands like 'test', 'sdist', 'bdist_egg' and so on work as intended, and the output can be adjusted using option `--without-master` (master is enabled by default). Also fixes various issues with manifests discovered when making 0.6beta1, leaving these releases somewhat lacking... Updated docs, readme and changelog. Hopefully this closes #383 for good... :-)
