Merged refreshAllPreferences into DashboardFragment. This hopefully makes it more modular to manage preference display logic in each dashboardFragment, and makes it more efficient to monitor category changes. Now subclasses needs to implement 2 methods: - displayResourceTiles(): for 'static' preferences from xml - getDashboardTiles(): returns a list of dashboard tiles and superclass will wire it up to preference screen. If getDashboardTiles() return null (aka no dashboardCategory available), the fragment will not attempt to monitor category change. The edge case is that if a package starts to provide a tile for this category, we will not be notified. I have not seen this case coming up. If we indeed need to handle this case, the category listener needs to have a way to monitor specific category rather than globally.
