Tiling: Add fallback path for the first Polonium tile. Commit. Fixes bug #488898

I’m a little bit surprised or confused here. Polonium is an external script. KDE/Kwin specifically addresses scripts? That’s actually wonderful, totally the opposite of what Gnome does (yes, I had to bring it up).

I stopped using Polonium, as it does not work perfectly fine for me. I’ll let them cook a bit more, its otherwise an excellent script/addon.
