Simpler, more reliable note lists

Notes now uses the list engine from Reflect for bullets, numbered lists, and checkboxes. Tab, Shift-Tab, Enter, Backspace, and undo follow one consistent set of rules.

At the outermost level, Shift-Tab removes list formatting and keeps your text. Existing notes retain their lists, links, checkboxes, and formatting. No data migration is needed.

The same editor is shared with the iPhone app. This release also includes a dependency security update.
