Real-time, immutable conversation state

[dmitrizzle]

Right now the chat bubble works fine, but there might be issues should the conversation options be updated in real-time or need to be more flexible. At very least there should be some sort of concise record of the conversation and user interaction besides computer RAM.

Note: it's still fine to have the system work as-is for now, but data records will need to be created in the following fashion

• [ ] Store conversation in immutable JSON object
• [ ] This object will need to be processed by our system in some way so that we remember user choices, where they at etc

After some thinking this would be an overkill for this project and adding Redux will seriously add a lot of weight. Additionally it'll go against the project paradigm of 0 dependencies. #47 should accomplish what's necessary (it'll produce a mutable array of a set length that will shift as new content is added)
