Automatically adding managed profile shortcuts to homescreen.

When the managed profile is created, a "Work" folder is created
and added to the homescreen. All work profile apps are added to this
folder and icons for subsequent installs (withing a fixed time frame)
are automatically added to this folder.
If this folder get deleted or the time-frame expires, icon for any new
install is placed on the homescreen.
