JavaFX on Linux needs libxslt.so.1

[olivierdagenais]

A user encountered the following error:

java.lang.UnsatisfiedLinkError:
  /path/to/jre1.8.0_60/lib/i386/libjfxwebkit.so: libxslt.so.1: cannot open shared object file: No such file or directory

...it would be nice if the JavaFX provider was able to detect this as part of its compatibility check, possibly by attempting to launch a WebView, to be sure it works.
