[NTG-context] back-up.lua; mtx-epub.lua

Hi all, in my attempts to validate epub export from my context source, I made the following changes to back-up.lua and mtx-epub.lua 1) the actual context language is put in the epub 2) changed the OPS directory to OEBPS. The 2.0.1 Standard does not actually say that is has to have that name, but I only found examples using that one, including the sample documents in the 2.0.1 white paper. 3) changed opf:scheme to UUID, since that is used and not a ISBN number 4) added the encoding info in the opf file 5) changed the single in double-quotes in the opf file manifest. I do not know if it is necessary, but this seams to be more consistent Andy diff back-exp_old.lua back-exp.lua 2370a2371
