Updates Terminal preferences to start with the Pro profile

Attempts to change the font to Menlo 18pt but mostly doesn't stick.
Terminal recipe References a remote file for the font

Also:
- Clears any application save state prior to updating the font
- Font changing now refrences the profile attribute instead of being
  hard coded
Clear preferences daemon

Finally we are getting our preferences to stick by killing a daemon that
was caching the old preferences and ignoring our changes to the plist.

Also adds setting to close window on clean exit.

Finally cleans up old attempts and killing daemons and files that we
thought were holding on to the cached prefs.

Skips & warns if Terminal.app is running
Adds butler installer and configures Butler as a Copy buffer

Adds dmg as a dependency in sprout-osx-settings/metadata.rb because
sprout-osx-settings::butler includes sprout-osx-apps::butler which
requires the dmg cookbook.
