replace creation of style and template classes with container calls

There are several files (f.e. phpBB/includes/bbcode.php) that manually create instances of some style classes:

$style_resource_locator = new phpbb_style_resource_locator();

$style_path_provider = new phpbb_style_extension_path_provider($phpbb_extension_manager, new phpbb_style_path_provider());

...

They should be replaced with calls to the container, where possible?

(But keep in mind, that they sometimes need and have a different context, f.e. abusing style classes for email templates. There need to be two different objects then.)
