New EXMARaLDA distributions

EXMARaLDA is currently undergoing major surgery: the tools have to be adapted to work with 64bit systems, OpenJDK and Java 11+. This is necessary, among other things, to make EXMARaLDA work with video support on MAC OS Catalina. After a lot of fiddling with the details, preview versions are available now on the Preview Download page.

As a positive side effect, video support on Windows is also improved: the new JavaFX player can now be used to work with MPEG-4 videos.
