For correct Translations

For correct localization of ‘tfk_subfilters’ list, in file ‘taskfreak\inc\classes\tools.php’ I have made some changes.

In function ‘form_links’:

1. At line 120:

$str .= '<li class="tfk_selected_filter">'.$label.'</li>';

must be replaced to:

$str .= '<li class="tfk_selected_filter">'.__($label, 'taskfreak').'</li>';

2. At line 123:

$str .= '<li><a href="'.add_query_arg($name, $p, $url).'">'.$label.'</a></li>';

must be replaced to:

$str .= '<li><a href="'.add_query_arg($name, $p, $url).'">'.__($label, 'taskfreak').'</a></li>';
