- Made dock/clip steal appicons of applications that were started from a

shell/xterm or from the main menu, if there is a docked appicon of that
  class that is not running at the time the app is launched.
- Added animation to show that the appicon was stolen by the dock (the way
  NEXTSTEP did - map an appicon as it normally would have been, then slide it
  to the position the docked appicon is).
- Updated the animation constants for scrolling/sliding/shading to better
  adapt to newer/faster machines. Also used wusleep(10) when the delay was 0
  to get rid of the jerky animation when there was no delay.
