Key names can't match Rails helper method names

[Hernán Schmidt]

When using keys that match Rails helper method names, like:

dom_id "le-dom-id"
url_for "le-url"

JSONBuilder calls the Rails helper methods instead of generating a key with the corresponding value.
Using key :dom_id, "le-dom-id" does not work either.

I have pushed up a fix for this and released a new version along with #8 and #9, it's now at 3.0.3.

You must use key :dom_id, "le-dom-id" or key dom_id("le-dom-id"), true.

Nice, thanks! =)
