Suggestion: Text Tokenizer Improvement for Quotation Marks

[HandOfCthulhu]

Books will often contain the following style of Sentence in English:
"That is a statement. So is this," said John Doe.
Everything inside of the quotation marks the user may want to have spoken by a "John" speaker, but the "said John Doe." segment spoken by the Narrator.
Consider using " as a sentence end token, or make it an option that can be selected in options before importing text.
