Expand VMware support to Workstation 9 (Linux).

The VMware builder should automatically pick between Fusion 5 and Workstation
9, based on which one is installed.
Missed a Mac/Linux incompatability

On the Mac ifconfig output is closer to "ip addr" in format, and so we need to
tweak the regex to work with the linux ifconfig output.  If Windows support is
to be added then this functionality may need to be pulled out into the driver.
Add support for CompactDisk and Headless

The driver has gained some new features, which we need to support.
