Add scripted tests for classloader-cache

Normally I'd include these with the previous commit, but the diff is so
large that I put them in their own commit. The tests handle 5 scenarios:

1) akka-actor-system -- a project that has Akka as a dependency and a
   simple main method that creates and terminates an ActorSystem. What
   is interesting about this test is that if scriptedBufferLog := false,
   we notice that the first call to run is slow, but subsequent calls to
   run and test are fast. The test does at least ensure that recycling
   the runtime layer in test works ok.

2) jni -- verifies that a project with native libraries will be able to
   load the library with each run. It actually swaps out the underlying
   library so that the it really ensures that the library is reloaded
   between runs.

3) library-mismatch -- verifies that the layered classloaders can work
   when the test dependencies are incompatible with the runtime
   dependencies. In this test, the test dependencies use an api in a
   library called foo-lib that isn't available in the version used by
   the runtime dependencies. Because of this incompatibility, the test
   will not work if Test / layeringStrategy := LayeringStrategy.Full.

4) scalatest -- verifies that a test runs using the scalatest framework
5) utest -- verifies that a test runs using the utest framework

The reason for (4) and (5) is to ensure that both the in sourced test
frameworks and external frameworks work with the new loaders.
