MUC: Switch to new storage format by default Changing the default setting of `new_muc_storage_format` from false to true. The code supports reading both formats since 0.11, but servers with MUCs stored using the new format will not be able to downgrade to 0.10 or earlier. The new format is clearer (less nesting for the most commonly-accessed data), and combined with the new map-store methods, allows for some operations to become more efficient (such as finding out which MUCs on a service a given user is affiliated with).
