Support for Orion browser in "Front Browser" actions and variables

The SafariTitle token should be the result of the JavaScript document.title.

The AppleScript for Safari (with error checking removed) looks like:

tell application id "com.apple.Safari" 
  if it is running then 
    tell document 1 
      set r to do JavaScript "document.title"
    end tell
  end if 
  r 
end tell
