- both files: remove \CJKindent which prevented the compilation with XeTeX, load the xeCJK package which is necessary to get text lines broken at the page margin
Both files are still compilable with pdfTeX because then xeCJk does simply nothing.
- Intro: replace TeX code by its LyX inset and alsoremove unnecessary document class option "cjk"
- the \LyX macro is no longer fragile since r37164, therefore preamble code can go
- some intro cleanups and fixes to have an uniform layout for all language variants
- remove some obsolete text from Polish and Basque Additional.lyx versions
