Title:
  Need a get_group_by_id() function

Status in Mahara:
  In Progress

Bug description:
  Unlike view/collection etc 'group' functions are not in a class.

  And so there is no easy function to find group information by id.

  Instead we do a db query each time we want to find some group
  information and by the looks of the code we are not consistent each
  time, eg:

    $group = get_record('group', 'id', $id, 'deleted', 0);

  vs.

    $group = get_record('group', 'id', $id);

  At current count there is over 40 places where we fetch group by id
  via direct db call.

  It would be useful to have all those places fetch the info via
  function. That way we can have consistency across the system and also
  allow for the replying with additional information such as roles and
  whether one can edit or not, eg:

   get_group_by_id($id, $includedeleted = true, $getroles = false, $canedit = false) {
      if ($includedeletd) {
          $group = get_record('group', 'id', $groupid, 'deleted', 0);
      }
      else {
          $group = get_record('group', 'id', $groupid);
      }
      if (empty($group)) {
         return false;
      }
      if ($getroles) {
          $group->roles = group_user_access($group->id);
      }
      if ($canedit) {
          $group->canedit = $role && group_role_can_edit_views($group, $group->roles);
      }
      return $group;
   }
