José Matox 6785e442cf Add support for input encoding handling by lyx2lyx.
Support all lyx files (support goes to lyx-0.6 the first public available lyx version).

Fine tune the guessing of the lyx version used to produce the document (only useful for 2.10 and 2.15 documents).

Support to convertion to utf-8 encoding was added but it is not (yet) active.
