* Fixes#6748.
* Implements SC_STONEWAIT to be used with OPT1_STONEWAIT.
* Removes a lot of hard coded OPT1_STONE checks now that the two states are split to their own statuses.
* Fixes SC_STONE not ending when the target receives damage.
* Fixes SC_STONE getting overwritten by other statuses the have OPT1 states.
* SC_STONE should damage the target by 1% of MaxHP, not CurrentHP.
* All skills that give StoneWait aside from Stone Curse are 100ms.
* Confirmed that Sienna Execrate is 8 + 2 * SkillLv seconds of Stone.
* Moves Provoke and Mind Breaker status clearings to the status database.
* Converts EndReturn in the status database from a boolean to a list of statuses. Statuses defined in this list will be ended and then the status making the call will not take affect.
