Mp3tag 3.33

What's new in this version:

- added option to skip resizing when adjusting album covers
- added support to resize to minimum size when adjusting album covers

- added command `Insert` to Web Sources Framework

Fixed:
- drag and drop from other applications did not work in some cases (since v3.32)
- added workaround for issue introduced by Windows Update where increasing the file size (e.g., when adding cover art) gave an error 380 for files on file systems backed by cloud storage (e.g., OneDrive or Dropbox)
- cover thumbnails in list of Tag Sources query results were not displayed in some cases.
- regression where previous compatibility adjustment of writing covers of type Artist, Media, and Icon for MP4 via Nero tags was no longer used.
- writing MP4 tags to specific fragmented/streaming MP4 files is no longer refused.
- writing MP4 tags to specific fragmented/streaming MP4 files corrupted the file and now simply refuses to tag the file.

- prevent server busy dialog from appearing during drag and drop when system dialogs (replace file, permissions) were shown (since v3.31h)
- restored drag and drop for apps supporting link operations only. (since v3.32a).
- output variables beginning with underscore were silently ignored at Web Sources Framework functions `SayFormat` and `UseFormat`
