fixed issue #1 (https://github.com/FunThomas424242/slideshow/issues/1) 

There is currently a dependency to junit4 but with eclipse kepler this does not work.
So i changed it to junit (see this thread https://github.com/infinitest/infinitest/issues/111).

To use a unique developer platform i have packaged a eclipse at:
