Version 2.0.0 beta - Release Candidate 16

This release is mainly a bug-fix and minor enhancement update.

Key changes;

• The biggest change is improved handling of servers that fail to stop within two minutes and enter a 'failed' state' Messaging to the user has been significantly improved. Striker allows a failed server to be forced off and the state cleared. Finally, scan-clustat will clear the failed state of a server once it is powered off (ie: from within the OS or after updates finished installing on the guest, as often happens with windows).
• New servers will no longer be destroyed on reboot, making it easier for users to interact with the server early in the boot process.
• Fixed a bug where trying to use the APC UPSes to power cycle or power off a rack while the Anvil! is offline was throwing an error.
• Improved anvil-safe-start's handling of storage that is in the 'disabled' state.
