Clojurians Log v2

@kingmob here's my PR for gloss https://github.com/clj-commons/gloss/pull/56 tried to be as non-invasive as possible. edit: rebased to fix test that was failing on master

I can submit a PR to update aleph too if you want, I see you're updating it as well though

aleph one seems small so I opened it https://github.com/clj-commons/aleph/pull/593
