Updated subcommands for leiningen plugin

I use 'lein repl' a lot, however since it did not recognize 'repl' as a subcommand, it very helpfully asked if I meant 'lein .repl' because there is a hidden file of that name. After some gnashing of teeth and unutterable mutterings, I decided to simply add the new commands in leiningen 1.7.0

This commit contains an additional 14 subcommands for leiningen 1.7.0
