Add restrict and unrestrict dialog

Add a fake unrestrict tip so we could reuse the BatteryTipDialogFragment
to build the unrestrict dialog.

After this cl, restrict dialog has two types:
1. dialog to only restrict one app
2. dialog to restrict more than one app

Will add dialog to restrict more than 5 apps when strings are finalized.
