fix relative path in CSS file

The Primo file uploader detects and manages relative URLs in the CSS
file, so prepending the '../uploaded_files/DAL/' part is unnecessary.
(and will be mangled by the uploader)
hide the CSS rule that hides the scopesList element

The scopesList element is meant to be hidden in the Simple Search and
shown in the Advanced Search for all other views.  This snippet is a
holdover from there, and does not apply to Dal's view.
