[tor-commits] [vidalia/master] Implement Icon Preference (appearance setting) in OSX (see #2163)



commit 4df4ee18c1acbc9fdad4e2395a8384190ff420db
Author: Jason Klein <trac.torproject.org@xxxxxxxxxxxxxx>
Date:   Sun Apr 17 17:13:25 2011 -0500

    Implement Icon Preference (appearance setting) in OSX (see #2163)
    
    Updated the Appearance settings page to include an Icon Preference
    group box with three new radio options:
      Show Tray Icon and Dock Icon
      Hide the Dock Icon
      Hide the Tray Icon
    
    In order to hide the Dock Icon, I had to create a custom Info.plist
    file with LSUIElement set to "1" so OSX would launch Vidalia in the
    background (without Dock Icon).  I then use TransformProcessType to
    force Vidalia to the foreground (show Dock Icon).
    
    Hiding the Tray Icon was trival. I only call "_trayIcon.setIcon"
    if the user wants to see the System/Tray Icon.
    
    By default, the user will continue to see Tray Icon and Dock Icon.
