I've made some improvements to the NUT-based fencing agent I contributed before.
The changes are:

- A more rigorous approach to the error codes returned by the agent.

- Added options to delay the times between issuing a poweron/poweroff command
and verifying that the UPS responds.

The revised fence_nut agent is at <http://pastebin.com/sQdqWKQq>.
