When using the --store-results option in runreport.pl, the resulting stored data would be more easily usable if stored as a hash.

So, say we have a patron named Andrew Fuerste-Henry and a report "select surname, firstname from borrowers." Currently, that will show up in saved_reports as:

[["surname","firstname"],["Fuerste-Henry","Andrew"]]

That makes it hard to do something like find all the surnames connected to a given firstname.

The data would be easier to work with if we instead stored it as a hash, like:

["surname" : "Fuerste-Henry" , "firstname" : "Andrew"]
