[ticket/15266] Fix events in content_visibility

Browse source 
Fixes core.phpbb_content_visibility_get_visibility_sql_before,
core.phpbb_content_visibility_get_forums_visibility_before,
core.phpbb_content_visibility_get_global_visibility_before

Does not modify the events, but fixes some comments, and changes
the rest of the function to allow (at least) the documented
event functionality.
