Require ostruct in Capybara::Mechanize::Browser

[tomstuart]

The #last_request method uses the OpenStruct class, so we need to load it first.

I don’t know why this didn’t cause problems sooner. Perhaps a dependency used to require 'ostruct' and has stopped doing so in a newer version.

Thanks! Makes sense, must be an issue with dependencies as you mention. Sorry for the slow turn around.
