Title: [feature/template events] Locate extension template events throughout current style tree

As it turns out, the user object is available to the filter class, and it
has the theme information, which includes the current style name as well
as the style tree of parent styles, so we can just use that information.

**Note** After pushing, I'm wondering if the current style name, gotten from $user->theme['style_name'] should be the last item of the array. Otherwise, won't the files in the rest of the styles tree overwrite it because they will be fetched after?
