Changes to SQM

[PabstMirror]

Any SQM change seems to generate a ton of merge conflicts
(I don't know a good easy way to add units without resaving the whole file, if someone does just let me know)
So just making this master issue to track what we want to get done

• add zeus slots #197 Zues - seems ready
• Add FAC unit marker #194 Fac - need a non-binned version I think?
• More spectator slots - todo

I doubled spectator slots in #197

Re: making SQM changes without messy commit: I figured it out but it's a process...you can just copy/paste the relevant parts from your change, but you need to include certain extra information to make it work

See chesh's comments in #197 for my attempt and eventual success
