[feature request] middle click on album art - open image with default viewer

[ghost]

would be a nice feature to have.

You can just make a custom shell command like so: ristretto --fullscreen %D/*cover*.jpg

Or maybe even more general solution: open with default viewer or have custom command (with custom arguments) for clicking. And going even further it could be done separately for left and right mouse buttons: could be very helpful with viewing with left click and editing with right.
