Add a new constructor public TextOf(final Iterable<?> iterable, String delimiter)

[tess1o]

Current TextOf has the following public constructor:

public TextOf(final Iterable<?> iterable) {
	this(
		() -> new Joined(
			", ",
			new Mapped<>(
				Object::toString,
				iterable
			)
		).asString()
	);
}

I propose to add one more constructor that accepts a delimiter:

public TextOf(final Iterable<?> iterable) {
   this(iterable, ", ");
}

public TextOf(final Iterable<?> iterable, String delimiter) {
	this(
			() -> new Joined(
					delimiter,
					new Mapped<>(
							Object::toString,
							iterable
					)
			).asString()
	);
}

I do understand that this has to be submitted as a pull request, but... :)

@tess1o https://github.com/yegor256/cactoos/blob/master/src/main/java/org/cactoos/text/Joined.java already does that, right?
