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">Halden is a totem-summoning shaman with an undying amount of work to do – his ghostly clientele provides him with plenty of unusual quests. Adventuring for the dead will take its toll on anyone. After all, wouldn’t you be a little off-kilter if you had to listen to restless spirits with unfinished business?
+
+
+    The Good: Halden can draw on the wisdom and power of countless lifetimes.
+
+
+
+    The Bad: His totems would like to remind you that he isn’t making up the voices in his head.
+
+
+The Red Dragon Inn: Allies – Halden the Unhinged brings a totem shaman to The Red Dragon Inn. Will you be able to master chaining his totems to maximum effect, or will your totem combos whimper? Take this off-kilter adventurer for a spin and find out!
+
+The Red Dragon Inn: Allies is a series of expansions for any standalone The Red Dragon Inn game. Each Allies set includes a single Character Deck, plus components to add a brand new character to your game.</div><div class="card"><div class="factrow"><b>where it lives</b> Library Kallax · B2</div></div><div class="card"><div class="factrow"><b>where it lives</b> inside <a href="../the-red-dragon-inn-5-the-character-trove/">The Red Dragon Inn 5: The Character Trove</a></div></div>
