info missing in project.clj files

Missing `:url` and `:license`... Hm. Actually, I don't see this top-level project at clojars --- only the components...

Of those components, conjure-util needs a `:url` and a `:description`, and most others are lacking a `:url`.

Perhaps they could all get https://github.com/macourtney/Conjure as their `:url`?
