install: setup.py fix + moved "default" dir in a "sat_templates" dir: the merge request at https://bugs.goffi.org/mr/view/3 was a good basis, but not fully working ("default" dir was removed), this patch fixes it, and do some improvments: - moved "default" in "sat_templates" dir, which correspond to the python module, so it can be found easily from python - added VERSION, and mercurial hash detection, in the same way as for Cagou and backend - slight modification of classifiers - replaces tabs coming from MR by spaces
