[gopass] Enable clipboard paste and entry submenu

Added opening individual gopass entries in a rofi submenu (default
Alt+Return). Allows copying any individual field to the clipboard, or
directly autofilling them individually as well.

Quick fill/copy is enabled from the main menu for usernames and
passwords individually.
