partial fix for various BUGs with going past the end of a viewing list... we now keep num_entries (of files) in pa_user_state, and use it to stop going before first or past last entry, even from viewlist, so this fixes many isseus... Final bug(s) are relating to multiple Dirs in a Path and its feeling too complex for no real gain, going to remove the feature, but for now, this version works / can be made to PROD

-        if count('new files') < say 1000 do eids, otherwise do path AND no new refimgs
+     * DECIDED TO DITCH multiple Dirs per Path, just adds complexity and not needed
+        - will address BUG-60, and last bit of BUG-83
