uploadQueue url needs passed through url()

I'm doing a POC for integrating plupload and node_gallery. I want to add a MENU_LOCAL_TASK at node/%/plupload that allows me to add images to a gallery. While #919482: create ability to assign parameters in the url, implement taxonomy term as an example would be nice, I can use nodeapi to accomplish this, but I stumbled over a bug.

On line 93, the URL is relative, so in this case the url evaluates to /node/%/plupload/plupload-pernode which is incorrect. It should become /plupload-pernode.

The attached patch does just this by passing it through url().
