Sort /pages alphabetically

Previously, the 'All Pages' view was not sorted alphabetically. We need
to sort on the lowercase version of the page names so that lowercase
names do not end up at the bottom of the list and are instead mixed in
alphabetically, as they should be.

Patches test/test_latest_changes_view.rb to include changes needed to
test alphabetical sorting.
