Create text input field

[dmitrizzle]

This chat engine is to be used with Watson NLC API so it needs to have an input chat field as an integrated feature or a plugin. These are the proposed steps to implement that.

• [x] Textfield that's designed to work with mobile & desktop screens
• [ ] Textfield has send button
• [x] Textfield input is animated up on Enter
• [x] Textfield evokes a custom function
• [x] Plan and understand API data chunking. Currently we have two JSON data sets in our API. As the skillet grows (especially with Watson responses) there may be hundreds of those; we need to make sure we're organized and each of those JSON documents aren't too big and we aren't loading them redundantly if the user requests the same thing twice over, for example.

The way this seems to pan out is that chunking will work like this: there will be "conversations" (each containing bot statements, questions and reply functions) like there are now. But there could be a multiple number of them and they could be loaded in real-time.

However, the conversation history still need to have an immutable record system of some sort. Also, it would be good to index all elements within each conversation. It would be good to have code review and discuss this a bit more; there's a chance things might get more complex and sphaghettier as this app grows.
