Print varargs in steps not as array, but as list of strings

[lanwen]

When use

@Step("Step: {0}")
public void clickOn(HtmlElement... elements) {
...
}

Expects: Step: ["Element1", "Element2"]
But: Step: [Lru.yandex.qatools.htmlelements.element.HtmlElement;@42ed46a7 occurs.

It will be nice to print varags as list of String

Dont forget about primitive types (int... ints)
