Bindings are technically for lisp-mode and scheme-mode rather than
slime-mode since evil-leader/set-key-for-mode doesn't seem to work
with minor modes.
- Use slime for indentation
- Add extension for SBCL
- Allow to create a common lisp scratch buffer with slime-scratch
- Enable fuzzy completion with score.
- Don't enable SLIME in Emacs Lisp. It's not usable. The SLIME of Emacs
Lisp is Emacs itself.
