- I've added some keys to \setupexport:

   author
   title
   subtitle
   firstpage (also new key in mult)
   lastpage  (aso new key in mult)

- The title, subtitle and author inherit from \setupinteraction which 
already inherits from \setupdocument (metadata namespace).

- In mtx-epub these variables are picked up (from the epub job 
specification) and firstpage / lastpage are added to the images list.

Nothing has been checked and the firstpage/lastpage image names have to 
be pushed into some epub metadata blob I guess but that's for you to 
figure out in mtx-epub. It's probably best to assume that the images are 
present and suitable for epub.
