AI 144181: Modify ProgressDialog class and its xml so that it follows the

Android's UI guide line. This modification is based on leland's mock.
  See http://b/issue?id=1748136 for more information.
  Put ProgressNumber left side, next to ProgressPercentage.
  Make ProgressPercentage Bold.
  Put ProgressNumber and ProgressPercentage near to the ProgressBar
  above. This is same as the design of Market application.
  Enable ProgressDialog change the ProgressNumber format. This is hidden
  since the interface is premature.
