Mp3tag 3.35

What's new in this version:

New:
- added support for RF64 WAV files > 4GB.
- added configuration option for replacement of folder separator used when renaming files from tags (see 'Options > Files')
- added support for spacer items when configuring toolbars
- added format string helper button and menu to import cover and export cover action dialogs
- added support for docking Filter left and right of toolbars

Fixed:
- renaming folders using `_DIRECTORY` at 'Convert > Tag - Tag' or action 'Format value' when running under Wine could silently overwrite duplicate files
- added a confirmation prompt when selecting an item from the Find window results list if there are unsaved tag changes and auto-save is disabled
- lists for tracks and files at Tag Sources result dialog did not always display their selection under Wine
- customize menu item from Tag Panel context menu opened wrong options dialog page (since v3.35-beta.2)
- regression where decimal `BPM` values were no longer truncated to integers when writing MP4 tags, which resulted in a user-defined `TEMPO` field being written.
- renaming folders using `_DIRECTORY` at 'Convert > Tag - Tag' or action 'Format value' was not supported when running under Wine
- MP4 atoms with empty content could not be modified or removed
- writing and removing tags failed with error message if path name could not be determined by file handle (since v3.34.1)
- field `TITLE` was always imported as `Title` from Tag Sources
- Discogs Tag Sources: prevent composer metadata from being carried over from the previous standard track into subtracks.
- after deleting the current directory from the Tag Panel directory field, navigating backward or forward via Alt+Left arrow and Alt+Right arrow still remembered the deleted directory
- icons for helper buttons in various dialogs were too small and are drawn with artifacts in some resolutions when dark mode was enabled.
- menu items in the Utils context menu were incorrectly enabled while an operation was in progress.
