Edit dialog: refactor

Browse Source 
* make previewer use a more generic Adapter to flip through cards;
* return Previewer from `show_preview()` for testing,
* as well as Edit dialog from `open_dialog_and_show_note_with_id`;
* disable/enable `Edit` editor buttons more reliably;
* a few minor changes
