Allow users more control over auto monitoring logcat.

To help users who don't know about logcat, we automatically monitor
logcat output to see if there are any errors from a user application,
and if so, display the logcat view.

This patch makes this feature a bit easier to use:
 - The first time the logcat view is about to be displayed, a dialog
   is shown that allows the users to enable/disable auto monitoring.
   Note that this can also be done via logcat preferences.
 - Users can now control the message priority that will trigger
   auto monitoring.
 - Once the logcat view has been displayed, we turn off auto monitoring
   until the next launch. This reduces overhead and avoids unnecessary
   change of focus in cases where the user is already interacting with
   the logcat view.
