Add support for setting up Arquillian Drone

[mojavelinux]

Setting up Drone is a bit of a hurdle for developers. Forge can simplify this by handling the necessary setup, just like with the core Arquillian setup.

1. Add the Drone BOM to the pom.xml
2. Add the Drone libraries (Selenium 1, WebDriver or Graphene)
3. arquillian.xml configuration for selecting browser

See the reference guide for details on the Maven configuration: https://docs.jboss.org/author/display/ARQ/Drone
