Use full node object in the url alias generation

Hi,
thank you for the work you have done building the module.

I've just tested it but I have a big problem, the module is actually not loading the full node during the alias generation.
So if I have a path alias pattern setted like this: 'blog/[node:field_category]/[node:title]' it wont count the category part so the alias will be generated wrong.

I've just made a little patch, instead of creating a fake object node we can prepare it from the node using "node_form_submit_build_node" function.
This will easely fix the problem and the alias will be generated correctly, please check out the patch.
