Damien Elmes 6680cdf1d3 update the card layout screen
- changes are now committed in bulk when closing the dialog,
and can be canceled
- it's not necessary to save the note to the database to preview it
- duplicate fields are now shown as duplicates in the top list
- redraw preview more quickly
- use + instead of _ when deduplicating names, as the latter is a
glob character
