Subject: Memberships element added.

For easier communication of a participant with its newly created
subparticipant I exchanged the community element with a memberships
element. Now the creating participant gets all necessary information of
its subparticipant to start communication right after creation. The
memberships element has the same structure as a resource representation
of /sys/memberships but there is only the newly created
subparticipant listed in the participants array (itsyou=true). The
/sys/memberships representation lists *all* participants (and
subparticipants) joining the same community.

After creating a subparticipant:

curl ... -H 'Content-Type: application/json' \
         -X POST -d '{"realm":"tux","communities":["stephan","public"]}' \
         https://.../sys/subparticipants

you get something like this as answer (example):

{
  "description": "Created from \"Teacher client\" (pid:3)",
  "community_selfrouting": false,
  "realm": "tux",
  "auth_ids": [
    {
      "desc": "Randomized authid",
