Caliper 0.1.0

The first release.

Added

• Widgets in the menu bar, each its own item that macOS lets you drag into
  place: CPU, per-core load, memory, network, disk capacity and activity, GPU,
  temperatures, power, battery, fans, and a clock.
• Cell styles -- text, graphs, gauges, bars and a core matrix -- with
  captions, icons, spacers and dividers, arranged in an editor with a live
  preview.
• A detail panel for the cell you click, desktop widgets that sit on the
  wallpaper, and threshold alerts that colour the strip and send a
  notification once a breach has lasted 30 seconds.
• Sharing: export a widget as a .caliperwidget file, and open one to see
  what it needs and whether this Mac has it before adding it. A file too big to
  be a widget -- too many cells, a name or caption too long, wider than a menu
  bar -- is refused with the reason, before anything is drawn from it.
• Launch at Login and About Caliper, from the status item menu.
• VoiceOver reads every menu bar item, desktop widget and detail panel, and
  alerts are underlined -- dashed for a warning, solid when critical -- so they
  never depend on telling orange from red.
• Ready for translation: every string is in a catalogue the tests check
  against the source, so a new language is a directory to add.
• Updates through Sparkle: one check a day, which the menu switches off, and
  every download verified against a key built into the copy you are running.
  That check is the only thing that leaves your Mac; the Privacy page of the
  documentation, linked from About Caliper, says exactly what it sends.
• Light on the Mac it measures: one timer for the whole app, hardware read only
  for cells that are showing, and sampling suspended while the display sleeps
  or the screen is locked -- and, one item at a time, while a full-screen app
  hides the menu bar of a single-display Mac, the notch hides an item, or
  windows cover a desktop widget. Alerts keep watching throughout.
