Unity System Compositor has two unsynced bug lists

Unity System Compositor has two unsynced bug lists.
<https://bugs.launchpad.net/ubuntu/+source/unity-system-compositor>
<https://bugs.launchpad.net/unity-system-compositor>

This unnecessarily risks quality: some bugs are only in one list, some people will know about only the other list, and even when a bug is in both lists they can have different importance levels.

For these reasons, Ubuntu Touch policy is to track bugs on packages, not projects.
<https://lists.ubuntu.com/archives/ubuntu-devel/2013-November/037821.html>

To fix this:
1. Go through each bug reported on the project, except this one, and move it to the package.
2. Mark this bug as fixed a couple of minutes in advance.
3. At <https://bugs.launchpad.net/unity-system-compositor/+configure-bugtracker>, change "Bugs are tracked:" to "Somewhere else".
