Replace uuid package with built-in Crypto library for generating UUIDs

[nelsonni]

Entities stored in the Redux store are currently uniquely identified using the uuidjs/uuid library, but this dependency can be entirely removed in favor of the built-in JavaScript Crypto library. Removing separate libraries in favor of built-ins reduces the package size, attack surface, and robustness of Synectic.

This PR resolves #1116.
