• Attempt to fix the auto-updating functionality with current installers (#194,
  @pkgw). The old method of launching msiexec /i doesn't seem to work anymore,
  resulting in an error with a refusal to reinstall an already-installed
  application. We'll put out an additional release so that we can exercise the
  changed behavior (which now uses msiexec /fvomus).
• Make it so that the auto-update setting can be controlled from the command
  line, using msiexec ... AUTOUPDATE=OFF to disable auto-updates (#133, #194,
  @pkgw). This should be helpful for scripted installations. (All settings
  besides OFF should result in the default behavior of auto-updating being
  enabled.)
