Refactors the confusion status effect. Removes "confusion strength" and replaces it with duration, which is measured in seconds.
This also allows them to use the adjust_timed_status_effect procs instead of their own.
Fun fact! 2 years ago when confusion was refactored into status effects, all confusion effects in the game were halved in duration. They were changed to status effects, which tick every 1 second by default, from life, which tick every 2 seconds by default, without any values changing.
