Rebase Boss MVP by @edgarssilva

Rebases #200 onto the latest master, with a couple subjective tweaks:

• Make boss flag in YAML a bool instead of an Option<bool>
• Impl HasLoadProgress for bool instead of ignoring the boss field
  in the metata struct.

Otherwise this is pretty much all just @edgarssilva's code.

@edgarssilva , you can push to this branch to do anything else you want to do with this before merging, if anything.

Also, the attack logic isn't great and can lead to odd behavior but I didn't worry too much since we are changing it later.

Ho your right sorry, totally went over my head.

You can require bors to pass before merging on the branch protection rules, which would prevent this from accidentally happening in the future. I've almost clicked it a couple of times before remembering I was supposed to tell bors to merge it:

Done, also should I enable "Require a pull request before merging" so that also doesn't happen accidentally.
