New setting: "Show program path"

Add a setting to hide all but the last component from the programme
path, leaving only the "basename". Makes htop more usable on smaller
screens, or systems with longer than average paths. Off by default.

"Highlight program basename" will still be respected, to further
visually separate process names from their arguments.
