Add binary-compatible methods to run scripted tests in parallel using
parallel collections. Parallel collections are not tuned and a default
of 4 cores is used for the `ForkJoinPool`. This can be a matter of
experimentation in the future but for now I prefer to stay with it.
The non-parallel methods are not affected by this change.
The changes to the scripted plugin have not been used, only the sbt
scripted plugin is using `runInParallel`. In the future, this change can
also happen so that plugin authors can benefit from parallel sbt
testing. This is not a priority for me now :)
This was already supported in the internal Scripted used by sbt but not
in the ScriptedPlugin. This is fixed by just copy-pasting the modified
parser. We will have to wait for sbt itself to be built using an sbt
with the upgraded ScriptedPlugin to be able to avoid the code duplication.
java.lang.Class#newInstance deprecated since Java 9
http://download.java.net/java/jdk9/docs/api/java/lang/Class.html#newInstance--
```
Deprecated. This method propagates any exception thrown by the nullary constructor, including a checked exception. Use of this method effectively bypasses the compile-time exception checking that would otherwise be performed by the compiler. The Constructor.newInstance method avoids this problem by wrapping any exception thrown by the constructor in a (checked) InvocationTargetException.
The call
clazz.newInstance()
can be replaced by
clazz.getDeclaredConstructor().newInstance()
The latter sequence of calls is inferred to be able to throw the additional exception types InvocationTargetException and NoSuchMethodException. Both of these exception types are subclasses of ReflectiveOperationException.
Creates a new instance of the class represented by this Class object. The class is instantiated as if by a new expression with an empty argument list. The class is initialized if it has not already been initialized.

To pass File => Unit callback across the classloader boundary
I am encoding it as a java.util.List[File] by overriding
method.
This was needed since Java didn't allow me to cast
from one classloader to the other.
