Add type dependencies

[OliverJAsh]

The TypeScript types depend on

• @types/react
• @types/react-redux
• @types/react-router
• @types/history

… yet these are listed as devDependencies, not dependencies, meaning the user will have to manually and carefully install the correct dependency versions themselves.

For this reason I believe these dependencies should be added to dependencies or peerDependencies.

That seems to be the recommendation here:
