Add shelves page to game library; refresh bggpipe export

Port the export's physical shelf layout (.wall/.orow/.ocell) into the
scoped embed.css so /mygames/?g=shelves renders the wall in true
proportions, using the cream board color and accent-purple links for
legibility on the dark theme. Includes a fresh bggpipe re-export (new
Etherfields and Red Dragon Inn titles, updated art). embed.js/embed.css
are untouched by the export.

 <div class="card desc">Working in fast-food is hell.  All the employees are zombies, and you can&#x27;t find a single brain amongst them.  Except for the brain part - there is, in fact, one brain - that&#x27;s the premise of Give Me the Brain!, a card game in which players take on the roles of zombies in a fast-food restaurant in hell.  They all have to complete a number of tasks before leaving work, and the work keeps piling on.  Even worse, some of the tasks require basic intelligence and there&#x27;s only one brain to go around.
