feature: complete union/intersection options for parent_fault filtering and set sane defaults

[chrisbc]

suggested sane defaults are:

• location-radii: take the the intersection of sets for selected locations
• parent fault: take the the union of sets for selected parent faults
• for a combination of location + parent fault filters: take the intersection of the two sub-sets

[chrisbc]

it seems that intersection isn't default for locations ....
