Also convert non core FluxBB tables (tables installed via mods, e.g. private messages) to UTF8 when running the db_update script. Note however that only tables with 'id' columns will be converted.
Now user post counts get decremented when deleting posts/topics. The post count therefore now reflects the user's true number of posts in the forum. This also prevents spammers from artificially increasing their post counts (by continuously posting and deleting their post).
Update pun_trim function to also handle numbers. Previously pun_trim would return an empty string for numbers.
