Corrections for #152

This isn’t a complete fix, it fixes:
- can’t edit a troupe
- can set a contact for anyone

Also -
- combos was not at all functional on the current public site, I
commented this out until we can fix.  We have no combos right now.
- the double row thing is actually from stupid user things - if the
user adds their persona twice to a troupe, they get it twice,  that is
annoying but unlikely.
- I went nuts with the Admin to make it display nicely.  It was somehow
cathartic.
- and I found that troupe act view didn’t show the info that is unique
to troupes - it treats everyone as a performer.
