Title: Add support for importing external wsdl

Recently I have to deal with `wsdl:import` element which specify another wsdl file to be imported.
The mechanism could be found [here](http://www.w3.org/TR/wsdl20-primer/#adv-import-and-authoring)

So I make a patch to get things work.
test files attached.
