Switch workshop over to React hooks (#47)

## Problem

Hooks have been out for over a year now. It's time to freshen up and modernize the workshop.

## Solution

Replace the React Fundamentals workshop with a workshop that builds a giphy search app using hooks. This meant that the redux and testing workshops no longer were applicable since they were based on something that no longer existed. They were also outdated too, so they got deleted.

However, the old workshop is now at the [`email-based` tag](https://github.com/benmvp/react-workshop/tree/email-based).

-Step-by-step workshops related to building React applications, all while learning fundamentals of the React ecosystem. Best if accompanied with live facilitation. 🙂

+A step-by-step workshop to build a React application, all while learning React fundamentals. Best if accompanied with live facilitation by me 🙂.
+
+## Exercises
+
+All of the exercises make use of [ES.next](http://www.benmvp.com/learning-es6-series/), so you may need to brush up on the new JavaScript features if they are unfamiliar. Each step in the workshop builds on top of the previous one. If at any point you get stuck, you can find the answers in the source code of the current step. Any step can be used as a starting point to continue on to the remaining steps.
+
+You can start at the [beginning](src/00-begin/) to get set up. Afterwards follow these steps:
+
+1. [JSX](src/01-jsx/)
+1. [Query Field](src/02-query-field/)
+1. [API](src/03-api/)
+1. [Lists](src/04-lists/)
+1. [Form Submit](src/05-form-submit/)
+1. [Components](src/06-components/)
+1. [Prop Types](src/07-prop-types/)
+1. [Custom Hook](src/08-custom-hook/)
+1. [Loading States](src/09-loading-states/)
+1. [Final Quiz!](src/10-quiz/)
+
+## FUNdamental Concepts
+
+- Using JSX syntax ([Step 1](src/01-jsx/))
+- Maintaining component state with `useState` hook ([Step 2](src/02-query-field/))
+- Handling user interaction ([Step 2](src/02-query-field/))
+- Making API calls with `useEffect` hook ([Step 3](src/03-api/))
+- Rendering dynamic lists of data ([Step 4](src/04-lists/))
+- Conditionally rendering components ([Step 4](src/04-lists/))
+- Handling HTML forms & form elements ([Step 5](src/05-form-submit/))
+- Writing readable, reusable and composable components ([Step 6](src/06-components/))
+- Type-checking props ([Step 7](src/07-prop-types/))
+- Factoring out logic from components into custom hooks ([Step 8](src/08-custom-hook/))
+- Leveraging ES6+ to maintain application state with `useReducer` hook ([Step 9](src/09-loading-states/))
+- Applying component styling with CSS classes (throughout)
