Mob Ability Sequences Again Again (I swear this time) (#68382)

Adds the option for cooldown action sequences which has a list of sequence actions, the owner of the sequence doesn't have direct control over any of the actions in the sequence but is still considered the owner of the sequence actions, the main ability simply handles calling whatever those sub actions should do.

Adds melee cooldown times to cooldown actions.

Cooldown actions now use bitflags so an ability can share its cooldown to multiple other types of abilities

Cooldown times are now handled by the base activate proc, cleaning up copy paste of StartCooldown()

Reworks the admin verb for adding cooldown abilities to where it has significantly more customization (and tells you to mark the mob you want to modify instead of just doing nothing) and also allows for creation of the new sequences, allowing entirely new and unseen abilities to be formed out of existing ones. Also adds a verb for removal of mob abilities.
