Fixed v0.2.4

• There seems to be a race condition in MatchMaker._init_member(). Sometimes, apparently a member has already been created, but the session ID is not available in the database yet. We added a hotfix to try and make this problem less severe. Now, GroupMemberIO.load will try to load the member data repeatedly, with a one-second sleep in between tries for 15 seconds before aborting. In most cases, this should give the database enough time to catch up.
