Minor changes

Fix some typos. Add links to the primary web site for various defined
terms. Re-order the terms list so the definition for React appears
before other React-related definitions

 #### React Component
 
 A React component is created by calling `React.createClass()` (or, `React.Component` if using ES6 classes). This function takes an object of options that is used to configure and create a React component. The most common configuration option is the `render` function which returns React nodes. Thus, you can think of a React component as an abstraction containing one or more React nodes/components.
