The Orator demo is broken because of a typo in the TTS dependency

The Orator demo ( https://build.fluidproject.org/infusion/demos/orator/ )is broken because the TTS dependency points at https://build.fluidproject.org/infusion/src/components/textToSpeech/js/textToSpeech.js instead of https://build.fluidproject.org/infusion/src/components/textToSpeech/js/TextToSpeech.js

The differences is just that the TextToSpeech.js file name should be heads up camel case instead of heads down. This isn't always caught when testing locally because of case insensitivity.
