 showTaskPane will be called multiple times for loading a map after a map
 has been switching for several times.

 This is because index page register MAP_LOAD event to register
 TASK_PANE_LOADED event. After MAP_LOAD event is triggered several times,
 the same function is registered to TASK_PANE_LOADED event with exactly
 same number. This is not as expected. We just want showTaskPane be called
 once when TASK_PANE_LOADED is triggered for one time.

 We should remove the MAP_LOAD event registering after TASK_PANE_LOADED is
 registered.
