A Rust client (#18)

* Initial commit

The client is currently only capable of registering for play

* Switch to serde for json serialization

* Parse all JSON messages

Or rather all messages sent in the game

* Switch to rust nightly for serde

This mainly solves the whole json parsing problem reasonably well

* Move move logic to snake module

* Add util functions

* Improve error handling in main

* Implement utility functions on map struct

And keep those that do not deal with the map in the util module

* Refactor and improve the maputils

* Add test cases to maputil functions

Also fix the snake panicking due to an incorrect unwrap

* Fix snake panicking due to bad unwrap

Missed staging these in the last commit...

* Add logging

* Add a heart beat to the client

Needs some proper error handling however

* Handle errors properly in main.rs

Also refactor to improve readability

* Print what is happening to console

* Add readme file

Also lock the package versions used and update to latest nightly
