Title: Change related_name to Site

As suggested by @mbrochh the related name of the Page->Site ForeignKey to avoid clashes.
There is no code in django CMS that rely on such relation (except a PagePermission queryset addressed here).
It needs docs as this may have potential backward incompatibily issues on externarl applications
