BREADCRUMBS
This part is to allow going back to the tool where you came from
in a previous version I used the table tool_list, but since the forum can access the
resource_linker from two different pages (newtopic.php and editpost.php) and this is different
from the link field in tool_list, I decide to hardcode this stuff here.
By doing this, you can easily control which pages can access the toollinker and which not.
