Updating requirements

[jansowinski]

Hi, great project!

I think it'll be worth adding two requirements to README:

• chromedriver - after just cloning repo, typing bundle and ruby run.rb I got errors about not having chromedriver in PATH, I think I'ts worth adding info about that to tutorial - it'll save some time to newcomers.
• If you have selected language other than English (UK) in facebook settings, this script won't work (see undefined method `location_once_scrolled_into_view' for nil:Nil #5 and PR connected with that), so I think it's woth adding line about it to requirements

[edited] - it's more informative now :)

Both are good ideas, will do those in the evening :)

So, I just added some lines about selenium and the language. You think it is good enough [tm] now?
