impl binop<Rhs=int> for Mint

[tamuhey]

It is pain to add two integers as Mint:

let a = 1usize;
let b = 2usize;
let c = Mint::new(a) + Mint::new(b);

Thus, I implemented Add<Rhs=int> for Mint and AddAssign<Rhs=int> for Mint:

let c = Mint::new(a) + b;

Yes, that's true. It is a pain.

According to these popular crates, It seems to be reasonable to implement Op<{integer}> and OpAssign<{integer}>.
