Added console&osx trove classifiers (as we exclude windows now).

Also fixed the project name in the description.
Moved logger to the top level in preparation for refactoring
Bit of refactoring to get the indent level down
Comment and logging improvements
Moved logging setup back into the class.

This way we can use the part's name: nicer.
pep8
Small symlink method refactoring
Only copying egg-info files instead of symlinking dirs.

Not everything is a directory: GDAL installs gdal.py into the system
path, for instance. Turns out that copying the egg-info files is
enough, so that's all we do now.
pep8
Moved option reading to the init.

This prevents 'unused option' warnings.
Returning files that we've added so that buildout can clean up for us.
Updated changelog
Removed environment classifiers as we work on windows again.
Merge pull request #2 from nens/reinout-cleanup
