Subject: Add AP argument to profile, also let ESSID arguments be regexps

* AP= arguments in profiles take precedence over ESSID= arguments

* ESSID= arguments regexps instead of literals. To avoid screwing up
  any currently working profiles, I restricted the interpretation as a
  regexp to just the new wireless-dbus connection types.

* But a global change involved in implementing this is that the
  connection up/down calls will be passed a literal ESSID (which of the
  local networks matches the regexp) as an additional argument.
