Title: [ticket/8319] Prepend Board URL to LOCAL_URL links to prevent abuse

The description says:
"The URL must be relative to the topic page and cannot contain a server name
or protocol."
We now enforce this and will added a new token RELATIVE_URL with the current behaviour.
Existing BBCodes are updated to the new replacement on update
