The filters are now remembered in localStorage

Every filter, the days and title included, is stored under
job_search.filters when it changes and read back when the page loads.
A stored field that isn't valid (missing, from an older version or
edited by hand) falls back to its default, keeping the rest. Clear
filters still goes back to the defaults.
