Campagin info page stats -- pending fix?
Right now the code for pending campaigns makes a query that doesn't work
if you do the whole campaign.
We need to rework ti more like
(snapshot_for_project p1,p2,p3,...pn) minus isparentof:(version blah and filename like x or version blah and filename like y...)
and hopefully that will run..
We should also factor out the generation of these dimension strings to common routines.
