[aur-general] Merge request: kwin-standalone-git + delete request

Merge https://aur.archlinux.org/packages/kwin-standalone-git/ into https://aur.archlinux.org/packages/kwin-git/ The KF5 branch has the standalone kwin improvements and is more up to date. Delete https://aur.archlinux.org/packages/python-sqlalchemy-0.4/ Out of date. One package depends on it, however that package is out of date too -- its latest version works with community/python-sqlalchemy just fine. J. Leclanche
