Simplify list construction in xul (provide a default map_row_to_columns function), give the option for using fm_IDL.xml for column definitions, and use dojo.date.locale for timestamp columns when using fm_IDL.xml.

Simple example:

Given this XUL:

<tree id="atev_list" flex="1" />

Then this Javascript will build columns based on the "atev" class:

JSAN.use('util.list');
var list = new util.list('atev_list');
list.init(
	{
		columns: [ 'atev' ]
	}
);

If we need to customize certain columns, we could do it like so:

JSAN.use('util.list');
var list = new util.list('atev_list');
list.init(
	{
		columns: list.fm_columns('atev', {
			'atev_id' : { 'primary' : true },
			'atev_run_time' : { 'flex' : 1 },
			'atev_isdeleted' : { 'hidden' : false, 'onclick' : 'alert("Boo!")' }
		})
	}
);
