title: Changing the mouse's i-beam cursor in Xcode 4
body: <p>With a dark color scheme in Xcode 4 the i-beam cursor (aka text selection cursor) is nearly invisible.  Is there a way to change the color of this cursor, either for Xcode specifically, or failing that, system-wide?</p>
  
  <p>It'd be nice if it would automatically change to a color contrasting its background too.</p>
