Compact view

[opk12]

In Quillpad you can long-tap one note and choose Compact view. The note will show the title and not the body. What about adding this feature?

If you want to add that feature it's not too complicated:

1. Add a note field named compactView.
2. Add a database migration to add the column to the table
3. In TextNoteViewHolder and ListNoteViewHolder, adjust the views so that they are hidden when the note is compact. Add a check for the compact attribute in NoteListDiffCallback.
4. Add an item in cab_note_selection.xml, connect it in NoteFragment.onActionItemClicked, add a method to the view model that updates the note in the database.
5. Add tests to keep good coverage.
