Fixes a Dock tile that should never have been there, and rebuilds the menu bar icon to match the other Imperator apps. The app is menu bar only, but Info.plist never carried LSUIElement, so LaunchServices gave it a Dock tile anyway. The menu bar icon was 23 x 16 against the 18 x 18 every sibling app uses, and its colon sat half a point right of centre because a 2pt dot cannot be centred on a 23pt canvas and still land on whole pixels. The icon now shares its outline, border weight and corner radius with imperator-free-games, and an acceptance check measures both against that app's own artwork. Signed with a self-signed certificate and not notarized, so Gatekeeper blocks the first launch: right-click the app and choose Open, or run xattr -dr com.apple.quarantine "/Applications/Imperator WidgetClock.app".
