search looses all breadcrumbs

[carin]

reproduce:

* front end
* go to a category and hit the search

expected:

* breadcrumbs reflect where the user is

current:

* breadcrumbs are empty (or to be precise contain the menu item for the search, which in most cases is part of a hidden helper menu and thus utterly confusing the user via the breadcrumbs display)

would be nice if the option agregasen you are in:

home / downloads / category / subcategory / file

at the head for greater navigability on the site in the section of jdowloads
