Fix issues with updating list when applications get installed while ManageApps is paused or stopped.

When ManageApps gets started, the list of installed apps is retrieved from PackageManager and
compared against the old list to figure out newly installed apps(since the app has been stopped) and
also to weedout stale entries of packages which might have been deleted.
Since the application objects themselves might have changed the list is usually refreshed with new objects.
Deleted applications are taken care of right away by just removing from the List adapter.
For newly added apps however, the size and label/resource info has to be loaded before being inserted in to
the list since the list is already sorted. So just remove these entries from the list for now and let
ADD_PKG message handle adding the new elements.
Make AppInfo a nested class so that it doesn't hold a reference to its enclosing class and
 we have too many such entries one for each package.
