Updated github path
git commit -m "FIX: Move install composer.json to use self.version.

Now that Composer has been fixed, self.version can be used as a dependency for framework
and cms in installer.  This simplifies our composer.json, and meanst that we can commit
composer.lock into the repo, as required.  An annoying piece of our release process has
been solved!
Merge branch '3.0' into 3.1
