Pull request for several features

[aptinio]

Hi Philippe!

I hope these new features get pulled in:

When a test fails, show the current URL in the report

• aptinio@33956577e25b9071b96d capture the current URL when capturing the system state
• aptinio@b2381db35093a1276be2 pad all toggable links inside square brackets for consistency
• aptinio@fc8fa5ee4ae572f927ce fix reported URL when it contains an equal sign

  Properly detect windows platforms (especially useful since the new RubyInstaller for Windows uses MinGW)

• aptinio@a18bad758245b8acda93 detect the other Ruby implementations on Windows
• aptinio@6754ef9dc7c7811a591e use RbConfig instead of the deprecated Config module

  New get_css_count method

• aptinio@479aff223e6fc76770e1 add Selenium::Client::Extensions#get_css_count
• aptinio@a41dbccb12d9e270db31 do not modify passed argument

Thanks, Aaron
