Origami v0.4.1

Install IRIX on any graphics machine from its own console: the user guide
now walks through it with screenshots. This release also fixes what 0.4.0
left broken. Octane with SI shows its console, the Onyx 350 and Tezro
reach the network, and the VPro pointer is visible. VPro and
InfiniteReality are faster.

Every machine is in the gallery.

• Fixed:
  • Octane and Octane2 with SI no longer start to a black screen.
  • An Origin 200 with IMPACT installs X and reaches the 4Dwm desktop.
  • The Onyx 350 and Tezro connect their onboard Ethernet.
  • A new Onyx 350 starts on its graphics console.
  • The VPro pointer shows in the PROM and in X.
  • VPro no longer draws lighter squares behind desktop icons.
  • /irix.cmds installs the machine's add-ons too, so an Origin 200
    with RAD4 gets its X server.
• Faster:
  • The VPro textport scrolls about 4x faster.
  • Fuel, Tezro and Onyx 350 keep normal guest speed under heavy GL.
  • InfiniteReality texture loads are about 11x faster.
• New:
  • origami nvram DIR reads and changes a stopped machine's PROM
    environment, such as console and AutoLoad.
  • show-command prints a QEMU command you can copy, edit and run, and
    [qemu] extra-args or --qemu-arg add your own options.
  • origami machines prints one table of the presets; origami machines PRESET shows the detail.
  • install-check probes remote media instead of downloading it.
  • create gives each machine a unique SGI MAC. Non-SGI MACs are
    refused.
• QEMU updated to 49b5ef3757.
