Make objectives a bit more reasonable

About the PR

• Reduces the amount of "multigrab" objects required to be stolen across the board
• Removes sunglasses stealing objective because it sucks
• Datumizes multigrab objective because it looked at me funny
• Removes hijack objectives from traitor and arcfiend and gives vampire and changeling unique versions that include their subordinate antags properly
• Reduces the number of assassinate targets on some objective sets
• Removes that one objective set that's just "be useless and die"

Why's this needed?

"Why don't people care about objectives on goon?"
The objectives: "Steal 5 tasers, assassinate 4 people, and hijack the emergency shuttle"

• A lot of the old multigrab values essentially required you to mechscan rather than steal them and often wouldn't even fit in your backpack.
• A lot of people on seeing hijack just immediately go "welp, not doing my objectives then". Changeling and vampire have a more reasonable shot at it and tend to do it in a more fun way than other antags anyway. (thrall armies are cool!)
• 4 specific assassinate targets is overwhelming, 2 or 3 is much more reasonable.

Objectives are meant to be a simple starting point or idea of some things to do, not complete round plans no-one will ever actually follow.

(*)Reworked a lot of stealing and assassinate objectives to be more realistically completable.

I really like the hijack objective for traitors, I like that its a harder to achieve objective that not many people can pull off, and it’d be a shame for it to just be gone entirely. That being said, it could be easier to achieve, maybe something like escape on the shuttle with at most 20% of the station population on board

You can still kill everyone if you want to, most people I've seen hijack didn't actually have the objective.

at most 20% of the station population on board

Veery hard to communicate whether you're going to complete or fail with an arbitrary threshold like that.
