tmfang 826879ed63 Create a preference controller for "App info"
We try to avoid managing too many preferences in a controller.
So, we create another controller to manage all apps info preference.

RecentAppsPreferenceController and AllAppsInfoPreferenceController
share same state of recent apps in order to improve the performance.

Test: visual, robo test
