Fix - on click item in story list goto right tab

On clicking on any item in the list of stories on either the user or admin sides you end up on individual.php at the last tab selected. This fix sets the indi-tab cookie to the value of the stories tab.

I'm not very proud of this fix and wonder if it may be a short term solution as I can see the Stories module becoming redundant when MarkDown is implemented, however it does work so as always I leave it up to you ...
