Upgrade to Leiningen 1.6.1.1
Upgrade to Leiningen 1.6.1.1

1.6.1.1 has an important fix for Clojure libraries/apps that use futures
and/or clojure.java.shell functions: before Leiningen used to shut down
internal thread pool Clojure uses for agents and futures too early,
that resulted in obscure java.util.concurrent.RejectedExecutionExceptions
being thrown.
