Merge pull request #12 from nburns/master

Removed problematic characters in json output
Adding query motifs for the bin status page. They assume the new fully-qualified structure for the bins collection (which has not been implemented yet) so they are commented out for now
Preparing the new list-bin-status view for the new fully-qualified bins structure, renaming the query motify to get bins with old data and making it more flexible
Correcting name of variable used in list-bin-status view to display the number of days which have passed since bins were checked
