Move PropTypes from 'react' to 'prop-types' library fast.

README.MD

If you upgraded react to latest version and got a warning Accessing PropTypes via the main React package is deprecated, and will be removed in React v16.0., but you import PropTypes from react package all over your project then check 3 simple regular expressions to find and replace in your project.

Find:

1. (import.+)(, \{ PropTypes \})(.+'react';)$
2. (import.+)(PropTypes, )(.+'react';)$
3. (import.+)(, PropTypes)(.+'react';)$

Replace:

$1$3\nimport PropTypes from 'prop-types';

"Replace" string is the same for all "find" regular expressions.
