Usage & Documentation

@digitalextremist I believe this could be a useful tool to advertise somewhere on the Celluloid wiki.. Every instance of RubyDNS is using this, and it solves the signal problem that we discussed some months ago, i.e. it does the correct thing w.r.t. signals.

Review the process-daemon usage documentation and the Celluloid wiki, which the issue identifies as the intended destination. Confirm where this tool should be mentioned and whether its signal-handling benefit is accurately described; done means the relevant wiki documentation contains a useful reference.
