Added error catching for bad user input on number of days. I.E., if you
try to filter by "bAd", you now get an error message prompting for valid
digits. Also I updated highlighting to use loop_context_vars.
Fixed filtering to work on either days, vendor or both. Previously, if
you selected a number of days, you had to select a vendor or else got
empty results. DOCUMENTATION NOTE: this supplies the expected behavior,
so specifying vendor is no longer required.
Changed filters form to GET method.
