[ic] [PATCH] Accept scratch variable in simple search with bar_link

[Doug Alcorn]

This is something I've done twice now.  This version is pretty
straight forward.  In the admin UI for the site layout you can specify
a simple search for the categories.  Typically this affects the
left-side links, but also some of the top links.  The usage is
something like this:

category=foobar

This does a search on the products table where "category=foobar" or
"sf=categroy/se=foobar".  OK, I think we all understand the way that
works.  What I've done is change it where you can add scratch
variables to the list of simple searches like this:

category=foobar
prod_group=[scratch my_prod_group]

The purpose is to let the user fill out a form somewhere that sets a
scratch variable.  You can then use that scratch variable to do
selective searches.  In my case, I'm building a cellphone accessories
catalog and want to limit category searches to those items that are
compatible with the shopper's phone.

Anyway, it's a simple patch to the bar_link sub.  I hope that either
1) Mike will commit this change to CVS so the next release of IC will
support this; or 2) Someone will come back with a way for me to make
this change local to a catalog so I don't have to keep patching IC
with each release. :)
