Modifer keys for mouse movement

[DanielHeath]

I'm testing a radiology application which assigns different meaning to mousedrag vs shift+mousedrag.

Currently that requires dropping all the way down from capybara to node.native.browser.page.command("Input.dispatchMouseEvent", to add the modifiers bitfield to the mousemove call.

Would a PR be accepted adding support for this?

My first thought is extending mouse.rb so you could call

Ferrum::Mouse.with_modifier_key(:shift) do 
  # within this block, all mouse events have the shift modifier added
end

I think it's good idea in some form! Which would be more appropriate can be seen from the code samples. Let's do it
