Minor refactor

Added new function to Game struct to simplify code in main game loop, replaced checking for all keys to just pattern matching a key, calling a function with it as a parameter and continuing.

* Changed struct constructions to use newer, idiomatic Rust
* Fixed up some single brach `match` statements to if lets
* Cleaned up match arms doing same thing
* More (Basically fixed up all the lints clippy provided that worked without breaking the program
* As can be inferred from above, added clippy as a dependency (Not enabled for compilation by default)

Also on success, generate random colour schemes animation
