Expose SBT Test Args to tests in the TestSuite

[russwyte]

It would be helpful to allow developers to have access to configuration details which are passed to the test Framework via args.

in SBT:
testOptions in Test += Tests.Argument(file("").toURI.toString)

Example:
def runner(args: Array[String], remoteArgs: Array[String], testClassLoader: ClassLoader) could forward the args array to the test suite and make it available - perhaps via an implicit similar to utest.framework.TestPath

This would allow tests to utilize values that come from SBT itself. Such as a URI to directory of the current project as above. The can be very handy when you need to functionally test things that require AJAX requests to a project file within a scala.js project.

One way to do this would be to expose a config map driven by -D{key}={val} args similar to the way scalatest does here:
