ui and other improvements. since last time:

    * ditched standalone html test and integrated widget with the
        homesearch page
    * adjustments to ordering at db-stored-proc level courtesy of miker
        (this MAY have solved a problem mentioned in the previous commit
        msg where when the filteringselect's onBlur is called, the value
        selected could change)
    * the mod_perl module now returns JSON instead of XML if it's asked
        to by an "Accept" HTTP header, and the AutoSuggestStore takes
        advantage of this
    * AutoSuggestStore actually uses the value in the search type
        selector now
    * the mod_perl module actually respects the limit parameter now

more still to come, including:
    * use openils.Searcher or similar to display class and field in the
        form "Topic (Subject)"
    * tie in selected org unit to request visibility searching from the
        UI layer
    * still investigate and fix numerical range problem
    * still overload validator to make it always return true
    * OU setting or some other such flag to enable/disable autosuggest
        UI bits in general
