Fixing get_unspent_outputs documentation

[DavidBurkett]

params[1] is the (optional) end_index. params[2] is the (required) max number of outputs to return. The documentation mixed up those 2.

Are you sure? Looking at the function below (line 500 wish) it is defined like this.

	fn get_unspent_outputs(
		&self,
		start_index: u64,
		end_index: Option<u64>,
		max: u64,
		include_proof: Option<bool>,
	) -> Result<OutputListing, ErrorKind>;

so the null is for the end_index.

It was [1, 2, null, true] which corresponds to: [start_index: 1, end_index: 2, max: null, include_proof: true]

But I'm changing it to [1, null, 2, true] which is: [start_index: 1, end_index: null, max: 2, include_proof: true]

Sorry indeed, I wasn't very awake at that moment :)
