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.

 The players add "dish"-cards or special cards to a common "order"-pile until one of them can´t (or won´t) add any more cards. Then that player has to "eat" the whole order by drawing the appropriate amount of cards from a draw pile. If he draws one (or more) of the "No More!"-cards, he accrues negative points and the round ends. 
 The played cards are then set aside and new "No More"-cards are shuffled into the (now smaller) draw pile, making for an ever more tense experience as the contest goes into the later stages.
