Sort the list of spaces provided by the /spaces URI
Sort the list of spaces provided by the /spaces URI

Sorted by name as they don't have any other attributes to sort
by. I considered using filter-based sorting here, but there is
no Space object, so it would take some significant fiddling to make
work.

This is for ticket #120
