Storing notes

[DrStrangeloovee]

Notes are going to be stored in JSON so this should be fairly easy to serialize and store in the database. EditorJS documentation regarding this: https://editorjs.io/saving-data/ The following needs to be done:

• [ ] Add save button to editor component
• [ ] Validate content before storing - see
• [ ] Notify user of successful save
• [ ] Automatically save note on title or content change
• [ ] Warn user if changes could be lost (on view change, etc...)
