Support arguments for methods inside templates

Methods inside templates could not have any arguments without causing an error.  Because of that, it would be impossible to write a function like:

<%= link_to "google", "http://google.com" %>

beceause lotus would error out with an ArgumentError.  The fix is to ensure method_missing passes any arguments along to the view instance.
