Various fixes, gear set unlocking and added ability to unlock mounts / orchestrion rolls

[miyuushi]

The EquippedMannequin db field is now used to determine how many gear sets are allowed to the character - this will have to be shared with the current gear set's index once I make a PR for that. Some actor controls were incorrect and missing, and two additional structs are now added. Other than that, there's just some new getters and setters for things I felt were missing, and some methods have an optional argument to not send update packets immediately since some functions shouldn't have that. insertClassIntoDb is also not hardcoded to level 1 anymore.

Oops. Orchestrion item doesn't work right, so ignore that for now. I deleted it

If you don't mind I'd like to take part of this PR and combine them into a later batch of 5.58 updates.

I don't mind if you keep me as the commit author or mention it somewhere at least

[collett8192]

Sure thing, as in my every "stealed" commit.
