Defining Actions without a Param causes strange errors

Documented here: http://pastie.caboo.se/141304

The client will report EOF because the server just fails to respond when it expects a response (rightly so).

The server will report:

Unexpected error while processing request: can't convert Hash into Integer

The server's method was defined as:

def test
  ok("Worked! You sent '#{@req.POST['foo'].inspect}'")
end

The method lacks an argument to hold the params. This should give a normal exception, but for some reason does not. This is a strange error.

In order to fix this, for now, all actions require a parameter. However, this needs long-term adjustment in the form of allowing for actions to nor require params arguments.
