v2.1.0

Added

• Complete integration with BrowserStack (includes tunnel creation).
• Tunnel identifier can be specified through PHPUNIT_MINK_TUNNEL_ID, when for Sauce Labs or BrowserStack browser configurations are used.
• Allow specifying Mink driver to use within browser configuration (the new driver parameter).

Changed

• Allow library to be used in projects with either Pimple 2.x or Pimple 3.x installed.
• The tunnel isn't automatically created, when using Sauce Labs or BrowserStack browser configuration and running test suite on Travis CI.

Fixed

• The Sauce Labs and BrowserStack unit tests were executed even, when their credentials weren't specified in phpunit.xml (affects contributors only).
