webosvbox: Suppress ssh errors

Whenever a new virtual machine is created, its RSA key also changes.
This results in "webosvbox ssh" failing with a notice to delete the
known-hosts record before trying again. It is then necessary to
manually approve adding the new key to the known-hosts file.

This commit suppresses host id checking so that "webosvbox ssh"
should always successfully connect to a running VM.

It also adds the copyright banner and cleans up some comments.
