0.26.7 seems to delete all NZBs imported from autoimport folder regardless of settings in Setup > NZB, and doesn't move them to default NZB folder.

NZBs from autoimport folder must be deleted or we'll enter loop. But files were not moved to default nzb dir, so I fixed few things. Final logic is something like this:
NZB from search engines ends up in default_nzb_dir
Imported NZB file stays where it was and isn't copied or moved to default_nzb_dir unless it was extracted from one of the supported type of archives. Then archive is deleted if you have 'Delete NZB after import' option checked and NZB is moved to default_nzb_dir.
NZBs in autoimport folder are moved to default_nzb_dir. Archives from autoimport folder that contain NZB files are deleted after extraction & extracted NZB file is moved to default_nzb_folder.
After the NZB is imported, 'IMPORTED' prefix is added to the NZB file if you have that option checked & NZB is deleted if you have 'Delete NZB after import'.
