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

+# SNAKE CLIENT
+
+Do you want the most annoying compiler ever?
+Do you want to constantly think of what is owning what variable?
+Do you want to stare angrily at the screen and wonder what the hell it means that some dumb value can't be moved?
+Then here is the ultimate snake client for you, written for the beautiful language Rust.
+
+## Requirements
+
+* Rust nightly (I recommend using [rustup](https://github.com/rust-lang-nursery/rustup.rs) to install it)
+* Cargo (should automatically be installed by rustup)
+* Snake Server (local or remote)
+
+The packages used have a tendency to sometimes break due to using the nightly build,
+so if it doesn't work try to install specifically: *rustc 1.11.0-nightly (12238b984 2016-06-04)*.
+
+## Setup
+
+A. Clone the repository: `git clone https://github.com/cygni/snakebot-clients.git`;
+
+B. Open: `<repo>/snakebot-rust`;
+
+C. Run the snake: `cargo run`;
+
+D. Improve the snake: edit `src/snake.rs`, and more specifically `get_next_move`.
+
+E. Debugging: see `log/snake.log` for all log output from the snake.
