Remove the release.py module and just use the field in app.yaml.template.
This is a DRY fix, to have the release /branches/ and /tags/ use a release
version that is compatible with the app.yaml file "version:" field.
Also, the steps for creating a release were simplified (with several steps
removed), and the release procedure moved to app/README, since
app/soc/release.py is now deleted.

Coverage: code coverage testing for Python
Coverage.py is a Python module that measures code coverage during test execution.
It uses the code analysis tools and tracing hooks provided in the Python standard
library to determine which lines are executable, and which have been executed.
