Refresh the screenshots, and Hans's description edit

All four listing shots were captured before the sheet-shadow fix, so each
carried the dark band along the bottom. Regenerated against the fixed
build; every one now measures a flat bottom band. The score sheet shot is
byte-identical and unchanged — an open sheet covers the bottom of the
screen, so the closed sheet's shadow was never visible in it.

Adds a fifth shot of the timeout, the most distinctive thing the app does
and the one state that had no picture.

Hans's description credits the design and the Chess.com inspiration.
Checked against F-Droid's documented limits: title 16/50, summary 66/80,
description 1644/4000, changelog 180/500, and <b> is the only markup, on
their allowed list.

.gitignore picks up *.swp and *~ so an editor swap file can't be
committed by accident.
