Checking for existence of allgroups_folder.sequence uses map.pm to check the file system instead of using navmap object to check current user's session. Locking added while allgroups_folder.sequence is being added, to avoid contention between two CCs adding the first group to a course at the same time. rat::loadmap() now checks for a return value of -1, as lonnet::getfile() returns -1 when the file is missing. Not sure when the existing branch (checks for -2) is triggered.
