[-]BO : bug color parameter in List

[-]BO : bug color parameter in List

In field list, if there is another field with 'color' => 'color_field', (and color_field column in the select), the background color is always the value of field list column 'color', never 'color_field'

the lines:
			{block name="td_content"}
				...
				{if isset($params.color) && isset($tr[$params.color])}
					<span class="color_field" style="background-color:{$tr.color};...
				{/if}

must be:
			{block name="td_content"}
				...
				{if isset($params.color) && isset($tr[$params.color])}
					<span class="color_field" style="background-color:{$tr[$params.color])};...
				{/if}

In the fields list, for display list, there is :
'osname' => array(
	'title' => $this->l('Status'),
	'color' => 'color',
	...
),
'color parameter gives the name of column in _List to be used as color background.
Currently, it is the same 'color' parameter which is used for one field and the row: (ex:osname)
		<span class="color_field" style="background-color:{$tr.color};...

But if there is another field with 'color' => 'color_field', (and color_field in the select), the background color is always 'color', never 'color_field'
That can be fixed with :
		<span class="color_field" style="background-color:{$tr[$params.color])};...

So the background color of the row (if colorOnBackground = true) and one row's field will be the value of the column given by 'color'=>'color', and The background color of others fields will be the value of the column given by their parameter 'color'=>'<color_field>'

$this->_select = '..color ..., ... color_field2 ...';

$this->fields_list = array(
		'field1' => array(
			'title' => $this->l('Status'),
			'color' => 'color',			// will also be the bg color of the row
			...
		),
		'field2' => array(
			'title' => $this->l('Status'),
			'color' => 'color_field2',
			...
		),
		'field2' => array(
			'title' => $this->l('Status'),
			'color' => 'color_field3',
			...
		),
