Move PropTypes from React package to prop-types

[mjclawar]

Description

This moves the PropTypes import from react to prop-types.

Example:

import React, { PropTypes } from 'react';

is now

import React from 'react';
import PropTypes from 'prop-types';

This will allow dash-html-components to support React 16+ by patching in different versions to the dash-renderer by the Dash developer (for now).

For example, in the application definition file:

import dash_renderer
dash_renderer._js_dist_dependencies = [
                {
                    'external_url': [
                        'https://unpkg.com/react@16/umd/react.production.min.js',
                        'https://unpkg.com/react-dom@16/umd/react-dom.production.min.js'
                    ],
                    'relative_package_path': [
                        'react.production.min.js',  # where the user has added this file to the installed dash-renderer for now
                        'react-dom.production.min.js'  # where the user has added this file to installed dash-renderer for now
                    ],
                    'namespace': 'dash_renderer'
                }
            ]

Changes

This looks good to me! I'm adding some standard dash integration tests in a separate PR so once that's merged into master let's just rebase this PR off of master so that tests run

[mjclawar]

OK. Just @ me when that's all set and I'll rebase.

[chriddyp]

alright @mjclawar - tests were added in #38

[mjclawar]

@chriddyp should be good now.

[chriddyp]

thanks @mjclawar ! I'll make a new release shortly

Nice! Did the same update for dash-core-components in plotly/dash-core-components#160
