* setup.py sdist now creates a pristine tar which can be used for release.
* Uses the version currently checked-out in git.
* Removed unneeded lines in manifest.
- There is a version.py included with buildd that is conflicting
with the deluge one. Rather than messing with sys.path it is
simplest to rename version.py to calc_version.py
* Webui will try to use debug files if deluge version contains 'dev'.
* Include webui debug files in sdist.
* Use exclude_package_data to remove debug files in release versions.
* Modify `git archive` to include all source code so that creating a
release source tarball is now done with `setup.py sdist` which uses the
MANIFEST.in file to determine files to be included.
