Foi contacts

Contacts now have a type (with 3 choices: foi, general, and media).  This is displayed and editable on admin.  General and media are not special but for an org foi contacts are:

a) ignored when added to the home page (we try to hide the ability to do this at all, but we can't hide it on create or edit).
b) extracted into a new section of the home page under the other contacts

We also pull the "FOI Releases" and "How to make an FOI request" links from the corp info sidebar down into this new section if it exists (they remain where they were otherwise).

You can set the contact type on worldwide offices, but it is not treated specially at all.  Is it perhaps worth just ignoring this and setting all the contacts for world offices / world orgs to be of general type?
