Add a to_hocon method.

[acidprime]

This gem currently doesn't seem to be able to contruct a file without loading a dummy file off disk. Most gems like json and yaml have a to_ style method that takes a ruby object like a hash and does a render on it. I think this would be a good idea to do this and mirror whatever .render does now by while accepting at least a hash.

rise from the grave, is there an alternative lib that bears this functionality?
