SelectionPanel: Allow date/time display formatting to be customizable.

[jng]

Currently this defaults to yyyy-mm-dd hh:mm:ss, the default locale-neutral wire format used by the mapagent.

In 3045:

Add support for specifying a custom date/time formatter function in the SelectionPanel widget. An example usage (format as d/m/y) would involve inserting something like this in the FUSION_INITIALIZED handler function.

Fusion.Widget.SelectionPanel.setDateTimeFormatter(function(dateStr) {

if (dateStr) {

var tokens = dateStr.split(" ");
if (tokens.length == 2) {

var dtParts = tokens[0].split("-");
var y = dtParts[0];
var m = dtParts[1];
var d = dtParts[2];
return d + "/" + m + "/" + y;

}

}
return "";

});

Fixes #663
