Feature #14033

Change in Community component:
* for each community space, a group of members is created in the mixed domain.
  The group will have as name the name of the community space and it
  will be referrenced by the community of users. The creation is lazy,
  meaning it is created only when the first user become a member of the
  community. A symbol can be set with the group's name to identify in a
  glance such group of members from the more usual user groups. A
  default emoticon is defined as such a symbol in the community settings.
* such a members group allows the users in it to be notified or for
  another user to have a glance of the members of the community. For
  doing, the members group is set automatically as a reader of the
  community space.
* the members group is synchronized with the users playing a role in the
  community space.
* the synchronization delay is removed.
* when a community space is removed (put in the bin), to be compliant with
  the standard behaviour in which all roles played in the space are
  deleted, both the memberships to the community and the members group
  are deleted.
* when a community of users (the application) is removed (put in the bin),
  the members group is also removed (put in the bin). In the case the
  community is recovered, the members group is also recovered.

A database migration step is added in which a new field, groupid, is
added in the table sc_community.

Because the creation of the members group is lazy, no script in the
migration is provided to create such a group for existing community of
users. The group for these communities will be created by
synchronization when accessing them.
