Improve handling of unformatted text

- do not assume any pasted text that includes a span is unformatted (nowiki)
- visually highlight unformatted text in editor
- disable adding format marks (like bold) inside unformatted text
- add 'unformatted' to text style dropdown

Fixes #190

Addresses but does not yet resolve #101
