Rework the metadata dialog to be more intuitive
Reason for the change
- Fix a bug where the lyricist value was not being saved when edited
- Rework the way tags are added to be more intuitive
- Fix a bug where the Create a Radio dialog incorrectly showed an error message
- Fix a graphical glitch when switching between read-only and modify mode in the metadata dialog
Test plan
- Open the metadata dialog
- Start modifying
- Add some tags, delete some tags
- Press apply
- Check the tags have been written correctly
Create a Radio:
- Open the Create a Radio dialog
- Enter a valid URL into the input box
Previously: an error message appeared even if the URL was valid. Now: the error message appears only if the URL is invalid.
