Add lanyards to tourist (also adds blob and cow mutantrace)

[Glamurio]

[Feature] [Respawning]

About the PR

This PR makes all tourists start with a lanyard in their ID slot, which contains their ID.

It also adds /datum/mutantrace/blob and /datum/mutantrace/cow to its possible mutant races, putting it in line with the Ambassador job.

Why's this needed?

Lanyards are cool, tourists seem like the perfect job for it because they don't start with a PDA.

Devilish sneaky change. I've got no problems with it though, and I'm sure it's a welcome change.

I didn't mean to be devilish or sneaky, my original intent was to add the lanyards, then I saw someone asking if mutant races might also be added to tourist, and since it's basically the same lines of code I figured I can group it. I'll atomize if necessary, but it just seems really minor that I didn't bother.

Seems good

i hope someone turns blob into an actual mutrace at some point and not just a human with less equip slots, a bad language flag, and a different sprite (that doesn't even fit with equipment overlays)

same with martian... my boys need some love

anyway, a welcome change
