Text-to-Speech Sanitation

[mxwllndrsn]

Need to check question and answer submissions for several conditions:

• Escape markup or special characters <special> to <special>
• Questions without answers and vice versa - throw an error indicating which row
• Limit character counts or total quiz length to prevent api overcharges and spamming
• Censor or reject profane or otherwise unacceptable content
• Any other valid test case

This is a reason, I think ultimately, for quizzes to be created and edited in-browser so input validation can be handled up front.

Sanitation will also depend on implementation in node vs python.
