Splitting ant

https://bugs.gentoo.org/show_bug.cgi?id=176856

So soon ant-1.7.0 should be hitting the stable Gentoo machines. The biggest benefit here is that full ant with it's big dependency tree shouldn't be pulled in so often any more. Not all of the packages are migrated to splitted ant yet but the most important ones like Tomcat are. If you are interested in how this works I recommend you to take a look at the Ant guide we wrote:
