More Fixes for Separate Update (#1487)

Browse source 
* handle getdents + fix condition + add info to description

* fix not handling dents errors

* to not overwrite it, only gather separate update entries when normal folder is done

* fix always setting entries to 0 and guest name including "UPDATE"

* reset indexes on completion

* don't use concat, fixes long standing bug

* make sce_module module loading take both paths into account
