For albums that are listed with a non-"main" artist first (ex: 37691520), the album artist replacement was returning an empty string. This isn't a problem with the default settings, but if you format albums into `{album_artist}/...`, the path becomes `/...` in this case, and is interpreted as an absolute path instead of a relative one, causing the download to fail.
This changes the logic so that if the `first_only` flag is passed, it will return after the first artist is actually added to the list, no longer returning an empty string.
* Updated `format_path_media` and related functions to accept customizable delimiters for artist names.
* Modified `Settings` class to include `filename_delimiter_artist` and `filename_delimiter_album_artist`.
* Enhanced `name_builder_artist` and `name_builder_album_artist` functions to utilize the new delimiters.
* Introduced `metadata_delimiter_artist` and `metadata_delimiter_album_artist` settings.
* Updated `name_builder_artist` and `name_builder_album_artist` functions to utilize the new delimiters.
* This allows users to specify their preferred delimiter for artist names in metadata.
* Introduced `url_ending_clean` to sanitize URLs by removing trailing "/u" or "?u".
* Updated `_process_url` and GUI search logic to utilize cleaned URLs for better validation and processing.
