binfmt_misc for executable jar files

Hello!

The applied patch updates the documentation of using binfmt_misc to
execute Java applications. It adds support for executable jar files, the
normal packaging for Java applications.

With Windows, you just double-click on the file, so Linux should be able
to run them, too :-)
