Versatile Cucumber step regarding hovering above elements

Here's a pretty useful steps that hasn't made it into Spreewald yet.

It is best used with the auto-mapper for BEM classes in features/support/selectors.rb

When I hover above [selector] element

CopyWhen /^I hover above (.*) element$/ do |selector|
  page.find(selector_for(selector)).hover
end

Example:

CopyWhen I hover above the album's image element

→ triggers a hover event on .album--image
