Replaced "Preferences"/"Options" with "Settings"

Replaced remaining "Preferences" and "Options" with "Settings" as
that is generally used for app settings instead of the system
preferences found in the preference panels.

Renamed Tracker's "Preferences" to "Tracker preferences" to be
similar to the entries in the Deskbar and e.g. the Media replicant
in the Deskbar tray.
