Allow module add custom css to the plugin extension configure page

[Robert Lyon]

When creating a module with configurable options we need a way to allow the module to add custom css to the plugin config page.

We need to be able to add css either by an external file or <style type="text/css"></style> tag

By adding the get_config_options_css() function, eg in your module:

public static function get_config_options_css() {
return array('<style type="text/css"> .mycustom { color: red; } </style>');
}
