[aur-general] Orphan request: gnome-shell-extension-shellshape-git, shellshape-mutter-git

The maintainer of those packages (Jussi Timperi) didn't respond to my email, so i thought "why not give it a try" I've got no experience with maintaining tarballs, neither in the AUR, nor elsewhere, but generally i am very active and would merge patches at any time.
