Enhanced field display for Nominatim search combo

This is the initial request from Eddy:

".. wondering if it is possible to apply some kind of filter to the results of 
the Nominatim request, in order to just display street, housenumber and 
postalcode in the result.

http://open.mapquestapi.com/nominatim/v1/search?format=json&q="Unter den 
Linden"&addressdetails=1&countrycodes=de&bounded=1&viewboxlbrt=13.08820,52.341,1
3.76,52.67&

This request results in very long string which contains information about 
village, city, country and even continent. Doesn't really make sense for me, 
because my application is just for one city.....
Maybe one of you guys has alredy stumbled upon a hint that'll do the trick :-)"

Indeed the current Heron.widgets.search.NominatimSearchCombo does not allow 
custom display of search results. The cause is that these three aspects need to 
work in cooperation:

1- the search URL parameters: see 
http://open.mapquestapi.com/nominatim/#search. "addressdetails" need to be 
provided to get formatted adresses

2- the combo Store: should be configured to contain addressdetails. Not just 
"display_name".

3- formatting both the dropdown list and final result: an Ext.XTemplate can be 
provided for "tpl" config, but this is only for the dropdownlist

The first two are easy to provide within the default 
Heron.widgets.search.NominatimSearchCombo via 
the "url" property and a new "storeFields" property. The third requires also a 
new "displayTpl" property to provide an Ext template for displaying the result. 
If all templates  are set to null, the old behaviour (using "display_name" will 
be used.

Actually work has already begun since this will make the 
Heron.widgets.search.NominatimSearchCombo much more usable! See attached 
screenshots for the following config:

        {
            type: "namesearch",
            // Optional options, see NominatimSearchCombo.js, here we restrict search to The Netherlands.
            options : {
                url: 'http://open.mapquestapi.com/nominatim/v1/search?countrycodes=NL&addressdetails=1&format=json&limit=3',
                xtype : 'hr_nominatimsearchcombo',
                emptyText: __('Search Nominatim') + ' Netherlands',
                tpl: '<tpl for="."><tpl for="address"><div class="x-combo-list-item">{road} {city} {state} {postcode} {country}</div></tpl></tpl>',
                displayTpl: '<tpl for="."><tpl for="address">{road} {city} {state} {country}</tpl></tpl>'
            }
        }
