Allow People to determine which roles count towards event full status

On event dashboard we should show following:

Counted (clickable link) = participant with counted status + counted role
Not Counted = participant with not counted status or not counted role
Not Counted Due to Status (clickable link) = participant with not counted status
Not Counted Due to Role (clickable link) = participant with not counted role

Note that I switched to the 'filler' field to leverage code for another option and that this field needs to be updated to a value of '1' for all existing roles to make them 'counted'

I kept the dashboard update pretty rudimentary - i.e I added a 'Other Roles' count and removed uncounted roles from the other aggregates.
