This release breaks the 'ovf' package's API. It also kinda breaks the top
level API as a side effect. However, this allowed me to make the
following improvements:
- Reworked and simplified the 'ovf' package's API. This makes editing
more reliable, and makes it easier to create and add support for new
editing functions - Now automatically detach CD / DVD drives to eliminate annoying vSphere
error / warning about disconnected SATA device
