Fixing useless extra HEAD requests
When searching for an artifact named "project" version "2.2.+" for organization "org", Ivy attempts HEAD requests for completely not possible versions.
IE: /org/project/0.9.2/ivy-0.9.2.xml
This is not terribly painful unless you have thousands of builds and are not on the same network as your ivy server.
Are HEAD requests even necessary?
Simply getting a directory listing should be good enough to determine if there is an artifact (for choosing latest-release). Now, after one is chosen, if no ivy.xml file exists, I could understand trying the next one, but trying all of them, just to select the latest one anyways seems like a complete waste.
