#3916 fix story/section links when no subdomain

[shane]

If a story's primaryskid is set to a skin which has no hostname (ie is not using a subdomain) the following is not done correctly:

links to the story will not include ?section=
the link to the section, itself, will not have the ?section=
the link to the section, has index.pl hard-coded instead of thisskin.index_handler.

this patch updates Slash::Utility::Display such that linkStory will add a section={foo} to the params hash, if needed. And the dispStory template needed 2 areas updated to remove the hard-coded index.pl and include the ?section=
