Rev 23: POWER DRAIN drains the number played; the troll punches walls; the first-person stack fits

POWER DRAIN's gain is the number played, BLUNTed or ABSORBed or not
(FAQ: the counter blunts the damage done, not the drain), and a wall
drained for its points gives them up too. Older games gave only what
the opponent lost and nothing from a wall, and replay so.

"This rock-hard beast can punch a player (or a wall, etc.)": a commanded
troll now punches a wall line beside it for a D4, once a turn — a new
command, so no old game changes.

Under the first-person pane the board strip could run into the dock on
a short or tall window; the pane now takes no more height than the row
can spare and the strip shrinks beneath it.
