feat(wibses): #4 Script listing

 Change script listing mechanism, scripts are listed by their names
(those one specified in script's parameters), not by it's file name
(as it was in previous version). Also, user can see now different
scripts lists for same files (if he change script name).
 All rest operations are performed using inner scripts ids now, which
are no longer depend on script file name, which can be anything valid with
"json" extension.
