Support for Rails :method in links

[rdeshpande]

Hi there,

Just added some basic support for Rails link_to methods that use the ":method => :foo" as part of the arguments. The change will check to see if the 'data-method' attribute is on the link and use that to make the AJAX request, defaulting to GET (as it was) if the attribute is not present.

Cheers, Rohan
