[wtp-incubator-dev] JUnit tests for XSL launching committed

[Jesper Steen Møller <jesper@xxxxxxxxxxxxx>]

Hi guys./

As I mentioned a while back, I've worked on a skeletal test plugin, 
which I now actually got working with Doug's current launcher code.

Get it from 
incubator/sourceediting/tests/org.eclipse.wst.xsl.launching.tests

It's simple, yes, but demonstrates a simple test which runs a simple 
transformation on a single input file and checks the output.
