Title: Use a semitransparent black shadow for embiggened tray icons

On X11, Psi previously added an opaque gray "shadow" to tray icons which
looks out of place on dark or colored panels. A semitransparent black
shadow should look cromulent on any panel color.

On the left is the previous shadow, on the right the new shadow.
