Stability Enhancement - Replace selection by class name

[karlgunst]

@abnoviello23

For stability reasons, we want to replace the use of find_elements_by_class_name or div[contains(@class)], google changes the class names regularly and it breaks our script

We should be able to select what we need using one of the following

• select by id (preferred method as this is unlikely to change)
• select by tag name (example <img/> for the image_url and <a/> for the url for sure can be used)
• select by tag position (for example we know the text content we want is under a > div > div > [div,div,div] (the 3 divs each contain the source, title, and description we need)

@karlgunst It looks like for this one, there are not many ids to go around, but I will change all of the class names we are using to full XPaths and tag Names.
