Gradle support for getting :web:test working properly

[Kevin Rushforth]

That's an interesting idea that might be worth pursuing. It would help 
mitigate what has been a long-standing pain point for developers who 
don't want to build media or web, but would like to run them. I would 
caution, though, that it is still not a substitute for building both 
media and WebKit yourself, since it will still not work reliably in the 
case where there is an interface change or some other mutually dependent 
change between the native media or web library and Java class files. In 
those cases you are stuck until a new EA build is available.

If you do want to pursue this, then as long as the dependency on 
org.openjfx:javafx-web and org.openjfx:javafx-media is localized to the 
downloading and unpacking step you mentioned, this would be fine with 
me. Maybe others could help test it on Mac and Windows.

As for the name of the new property, maybe STUB_RUNTIME_OPENJFX? The 
easiest way to implement this might be to set the value of 
`defaultStubRuntime` to the directory into which you unpack it 
(underneath either build or buildSrc/build).
