defaultProps & propTypes are static

rdp => static defaultProps = { }
rpt => static propTypes = { }

Class component correction, state is exact

• rwwd should not have a constructor, nor initialize state
• est empty state type is now an exact type

Exact Props & Named stateless components

• Props are now exact types
• Change functional stateless snippets to create a named function, rather than arrow syntax

Remove PropType Component Snippets

• Remove PropTypes from component snippets. I mean, we are using Flow, right? I've left the standalone PropTypes snippets in, as I'm sure there's some edge case that I'm missing

• Removed some Component snippets targeted explicitly at PropTypes

Properly Type lifecycle methods

• Update lifecycle method snippets to prompt user for Props & State type
• Correctly populate Props & State types for Component snippets
