Gantry 0.13.0

Added

• Machine detail view. Selecting a machine now opens its details — facts, an
  Inspect tab, and an editable CPU/memory panel — consistent with the Containers
  section. Editing CPU or memory applies via container machine set and restarts
  a running machine so the change takes effect immediately.
• Set CPU and memory when creating a machine, via new steppers in the Create
  Machine sheet.

Changed

• The menu-bar icon and the menu-bar panel header now use the Gantry app icon
  instead of a generic glyph.
