Add a collapsible checkbox preference for deletion helper.

Browse Source 
This adds a custom preference group which has both a checkbox
and collapse/expand behavior. This is intended to be used in
the deletion helper for apps deletion and downloads folder
deletion.

This patch implements the apps deletion integration.
