ranger: add imagePreviewSupport option and make previews work out of the box

Browse Source 
Before one had to turn it on manually and update the preview script in dotfiles
manually when ranger updates.

Now it requires zero configuration. Just run `ranger` and it works, and
should continue to work automagically when ranger updates.

Everything still can be (de)configured via `rc.conf` in dotfiles.
