Support implementation of Microsoft WebDriver

Selenium team adds support of Microsoft WebDriver in 2.43.0. Drone should use this vendor as well as selenium.

My Idea is:
1) An user is responsible to install MS WebDriver
2) Arquillian.xml presents new property (for example: IEDriverEngine). The values are LEGACY, VENDOR, AUTODETECT. The default value is LEGACY or AUTODETECT. I prefer AUTODETECT.

Unfortunately, this feature is not fully supported by Selenium for Java platforms (see comments).

Solution for branch drone 1.3.x:

• for enabling property in arquillian.xml:
  • add new field (attribute) in class WebDriverConfiguration
  • add setter and getter for this field
  • Note: properties in arquillian.xml are automaticaly mapped to fields in this class
• map a value of ieDriverEngine property to system property "webdriver.ie.driver.engine"
  • in class InternetExplorerDriverFactory
