Bug #166939 r=rginda

works with any AIM client, if they support goim: uris.

from cavin:
  1) a bunch new card attributes
  2) back end AB changes for AB Sync

from naving:
  1) Screenname -> nscpaimscreenname mapping for LDAP
  2) assertion fix to nsAddrBookSession::AddAddressBookListener()

from me:
  1) addressbook advanced search features, like "any name", "any number", "organization", "title", etc.
  2) add screen name support (UI, import, export) to mozilla, remove it from the ns tree.
  3) don't allow drop onto non-writable (LDAP) addressbooks
  4) bunch of code cleanup
