3 small bug fixes

1. **Duplicate document** 🐞 - When duplicating a document, there was a bug that sometimes caused weird characters to show up in your new document. No longer! 2. **Describe** 🐛- Selecting the first word in a document and asking Sudowrite to describe it used to make Sudowrite very upset. Now it will gracefully describe that word. 3. **Story Engine braindump** 🦟 - Very long braindumps in Story Engine were causing errors on rewrite. Now they work great!
