change photo filler to group of people when reporting PAC data

[stochasticTreat]

I just added two fields to the general campaign/candidate output so that we can show an image with a group of people when reporting data for non-candidate committees.

here are the :
"committee_type":"PAC"/"CC"/"CPC"
"committee_subtype":"Measure"/"Political Party"/"Recall"/"Miscellaneous"/"Initiative Petition No. Petition No. 6 - 2012"/null
Hit this endpoint to see it in action:
