- Changed the status_change structure to use dynamic rather than static memory to hold the individual status changes, this should have a noticeable impact on the server's memory consumption.

- Had to add a few 'ugly' flags to status_change since now you can't track SC related information while said SC is not active (happens only for Storm Gust, Joint Beat and Magic Power).
- Since I am unable to fully test, watch out for any bugs~
