The product, module path (github.com/yetone/magpie), binaries, env vars
(MAGPIE_ADDR, MAGPIE_DEV_UI, MAGPIE_THEME, MAGPIE_DEBUG), config and cache
folders (~/.config/magpie, ~/.cache/magpie), bundle id (com.yetone.magpie),
gateway provider id and token, and every UI string now say magpie.
On first run magpie copies ~/.config/dial and ~/.cache/dial to the new
folders when they don't exist yet (copy, not move, so a still-running dial
keeps working; the old folders can be deleted by hand later).
The logo is a small round magpie in profile: one path for the header and
the tray, and the app tile adds the white belly and the blue-green tail.
The header mark is drawn in ink rather than the accent colour, which
fought the text in light mode.
