VMPane 1.0.0-beta.2

Fixes for the first beta.

Fixed

• Deleting or cloning a VM that was shut down from its own window works: VMPane first quits the VM's process,
  which stays open after the VM stops (1.0.0-beta.1 refused with "VMRunning()").
• A Windows VM's guest agent comes back at once after the VM resumes from a suspend or a live snapshot is
  restored, without a Windows restart (works with the 1.0.0-beta.1 agent too).
• The VMPane folder in Application Support is private (0700) again: 1.0.0-beta.1 could make it readable by other
  accounts on the Mac (the files in it were already private). vmpane doctor reported it.
