FIX: If movetitle contains invalid characters than there are problems when creating/moving subfolders! i.e title "Die Nackte Kanone 2 1/2 (1991)" --> folder with unwanted subfolder "2": \Die Nackte Kanone 2 1\ 2 (1991)
Feature: Extra-Sortfilters settings are now saved
Fixed: Worldwide title setting may actually overwrite preferred language

Improved usability of moviedata scraper settings page - settings should now make more sense (removed duplicate settings, renamed few settings to be more clear for user, moved IMDB only settings into IMDB scraper)
