- added confirmation to removing bbcodes

- added optional MX and DNSBL checks
- added backtrace (triggering sql error) on error within sql_in_set as well as making sure it is handling an array
- let users having f_list access to a forum actually see the forum without a topic list and not displaying an error message - this allows for giving people access to subforums but not the parent forum without the need to add the (sub-)forum to the index.
- some additional bugfixes
