Have chat bot scripts live in a config file, or as individual files

[byrnereese]

Let's pull script text out of the code base and have them live in a yml file, or on the file system. This may help with localization in the future, but mainly will just help people edit scripts without the potential to harm code.

Good idea. Since this will be useful across any type of bot and is not specific to the voicemail use case, we should track this as a requirement for the bot framework in a separate repo when we have it.

This is also related to having pluggable skills / intent sets (from different packages, like external NPM modules) and using external NLU engines like Dialogflow, Lex, LUIS, etc.
