Added Axios + Logging & Testing Frameworks.

Browse Source 
Rewrote mojang.ts to use axios. This included creating a more robust error handling
system and response payload structure. Also included unit tests.

Added axios (HTTP Library to replace request)
Added winston (Logging Framework)
Added mocha (Testing Framework)
Added chai (assertion library)
Added nock (mock server)
