Builds the htmlpurifier safe iframe regexp from a list of sites stored in the database, instead of a hardcoded array. Each site in the safe iframe list is associated with a name. This will allow several regexp items to be grouped together under the same name when they're matching urls from the same site. Additionally, the domain part of each site is stored in a second list along with the names, so that it will be easy to fetch the favicon for display in places such as the external media block configuration form.
