renamed pa_pref to better named pa_user_state, changed code to adapt and made new_view and viewlist work with newer Options/pa_user_state - still more work but it should be functional again

 ## GENERAL
+    * for below.. make Options( request )
+        - know that a view is a "path", dont rely on orig_url
+        - remove all "Options()" that are not set by a user-choice in the F/E and just make sure new "OPtions" sets all defaults as needed
+        -- viewlist can work out new view_eids server side, and pass them back as json data
+            - can consider an optim-- new_view page makes calls to viewlist to ADD json data only, so only trigger a new "viewlist" if we dont have data for that part of the eids

     * going forward into search page (and probably all POSTs) does not work 
         don't render_template instead do a redirect to a GET of the new, or list? for del...

     * optim to not run_ai_on_* for scan, needs to make sure last run_ai_on actually ran/worked - might have failed (or in my case was marked stale and I cancelled it)
         -- also the case for get file details though, need to make sure last one was completed
