make test environment. Exports with luatex and xetex.

In successful cooperation with Scott Kostyshak.
We provide many lyx-documents which are not compilable with luatex or xetex.
But some of them compile, if we change the font use to non_tex_fonts.
Since this would change the appropriate source, we have to convert
it first into a save location. To make it there compilable,
we have to convert also all file references.
languages     used font
he|el|ru|uk  'FreeSans'
fa           'FreeFarsi'
zh_CN        'WenQuanYi Micro Hei'
The whole job is done with a perl script.
