Windows: no console, app icons, Calc tiles paint, theme switch no edit

Release apps use the GUI subsystem; workers, Git and cmd start with
CREATE_NO_WINDOW. Each exe embeds its icon as resource 1, which gpui
also loads for the window. Patch 0044: Win32 devices take no client
buffer, so tiles and slide layers paint at full size, then copy.
ely.xcd gives both schemes one notes colour: Calc rewrote the comment
style on each switch and left an undo step. lo-patches.sh keeps LF.
