translation ui css is loading unnecessarily

[datapharmer]

If a non-translator views a page transposh.php loads the translation UI css even though it serves no purpose. Modifying the add_transposh_css function should correct this condition which will save ~22kB of bandwidth for affected users.

An example that should prevent the jquery-ui from loading is as follows:

{{{
    function add_transposh_css() {
        if(!$this->is_editing_permitted() && !$this->is_auto_translate_permitted()) {
            //translation not allowed - no need for the transposh.css
            return;
        }

        //include the transposh.css
        wp_enqueue_style("transposh","{$this->transposh_plugin_url}/css/transposh.css",array(),TRANSPOSH_PLUGIN_VER);

	//Only load translation ui if user is a translator
	if(current_user_can(TRANSLATOR)) {
		   wp_enqueue_style("jquery","http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/themes/ui-lightness/jquery-ui.css",array(),'1.0');
        }

    }
}}}

You have a point there, but my guess that this line should only be removed in the case that the progressbar is disabled and editing is not permitted. Added such a line to code, will commit later
