Initial skeleton of 'setuptools' package, for installing dependencies, etc.

Cleaned up data file installation handling: we now just set extensions,
and all data files contained in packages are installed automatically.
Additional wildcards or filenames can be defined on a per-package basis.
Also, fixed some broken installation bits for ZConfig.
