Add constructor option to force HtmlUnit to download images on every page load

[stiemannkj1]

Every browser that I use with (Firefox, Chrome, PhantomJS, and JBrowser) Selenium automatically downloads all images on each page. HtmlUnit does not download the images. While I appreciate the design choice to avoid downloading images (it certainly seems like it would speed up page loads), this behavior is inconsistent with other browsers and causes HtmlUnit to fail tests that other browsers pass. I am requesting that a constructor option or (Capabilities) capability be added to HtmlUnitDriver to specify that it should automatically download all images (similar to HtmlUnitDriver's constructor option to enable JavaScript).

One way to accomplish this task would be to run this code every time a new page is encountered:

DomNodeList<DomElement> imageElements = htmlPage.getElementsByTagName("img");

for (DomElement imageElement : imageElements) {

	HtmlImage htmlImage = (HtmlImage) imageElement;

	try {

		// Download the image.
		htmlImage.getImageReader();
	}
	catch (IOException e) {
		// do nothing.
	}
}
