Title: Support method for rendering screenshot

Some drivers(Such as [capybara-webkit](https://github.com/thoughtbot/capybara-webkit) and [poltergeist](https://github.com/jonleighton/poltergeist)) supports the method for rendering screenshot.
If it is supported by `capybara`, the interface between each drivers is uniform.
And I can write the spec that has highly compatibility.

I added `render` method to `Capybara::Driver::Base` as well as [capybara-webkit] and (https://github.com/thoughtbot/capybara-webkit) and [poltergeist](https://github.com/jonleighton/poltergeist)).
