use redux for NoteCreator state management (#494)

* use redux for NoteCreator state management

This fixes a bug where the modal closes while replying to a note. This happens if the thread re-renders while you are replying.

Drafts of notes are also now automatically saved unless the user clicks the cancel button.

* fix modal closing bug

* really fix modal closing bug

* fix rebase
