Clojurians Log v2

Keybinding updates for the Clojure layer are now part of develop branch. https://github.com/syl20bnr/spacemacs/pull/13215 There is a new menu, SPC m m or , m for managing REPL sessions with sesman. This includes info about the current repl, a repl browser and lots of linking and sibling repl goodness for those who work on multiple related projects concurrently. The format menu is now SPC m = or ,=, which is the convention across all languages. I also added a few keybindings that were missing, including formatting for edn files. A few other keybindings have changed to follow convention, but hopefully these won't affect your workflow too much. I have also greatly improved the layer documentation, so it should be a lot more helpful in understanding the layer and how to use it.
