Changelog for MMM 2.x

• Fixed usage of wrong state name in set_active, forced_move_role and set_offline which could lead to strange errors when hosts had replication backlog.

• Added manual mode (bug #531011), wait mode, config values 'mode' and 'wait_for_other_master'
• Don't die at startup when no network connection is available - wait for it to appear instead (bug #416572)
• Changed startup behaviour. mmm_mond will only go into passive mode if it detects the active_master_role on more than one host.
• Added config value 'careful_startup' (bug #422549). If set to 0 mmm_mond will never switch into passive mode at startup.
• Added check for invalid agent commands (prevents crash when mmmd_mon version 1.x talks to an 2.x agent).
• Fixed date format for 'mmm_control checks' (bug #531841)
