Sumi v0.1.0

The first build. It does one thing: a black island at the top of your screen that shows the time.

Added

• The island, centered at the top of your main screen. Clicks beside it reach the window underneath, and it never takes focus from the app you're using.
• The time, in your language's format.
• A tray icon to quit.

Known limits

• Main screen only.
• No settings and no automatic updates yet: install new versions by hand.
• Windows warns about an unknown publisher, because the installer isn't signed yet.
