Added 'commit-release' hook.
If your local interface, you can define a section with extra release actions, like this:
<release:management xmlns:release='http://zero-install.sourceforge.net/2007/namespaces/0release'>
<!-- Update the copy of the version number stored in hello.py -->
<release:action phase='commit-release'>sed -i "s/^version='.*'$/version='$RELEASE_VERSION'/" hello.py</release:action>
</release:management>
Actions in the 'commit-release' phase are executed just before committing to the SCM the revision that will be tagged as
the actual release.
