Rich text editor

[vkbo]

Implement a rich text editor widget which has basic text formatting and saves to a rich document format.

The initial implementation must support:

• Text paragraphs and headers
• Bold, italics and strikethrough.
• Left, right, centre, justified text alignment.
• Paragraph and first line indentation.

The format must allow for future extensions to allow for versioning, footnotes, highlighting and annotations.

The editor must allow settings meta data. The document meta values must include:

• A title that is independent of any titles inside the document.
• A type declaration that identifies it as a Book, Partition, Chapter, Scene, Page or Note.
• The ability to link the document to notes or other notes.

The document file should support saving the meta data, but the data must also be considered backup or duplicate and the authoritative data saved in the project structure files. The ind-document copy of this data will serve as a backup in case the document needs to be re-included into the project after data loss.
