ANT integration not working without undocumented dargo dependencies

According to the docs, the ANT integration should work with just the cargo core uberjar + the cargo ant jar.

However, ANT will fail with classnotfound exceptions unless I also add commons-discovery-0.4.jar and commons-logging-1.1.jar.

The documentation should be updated + dependencies should be put into the uberjar or a seperate cargo-dependencies jar should be added.
