helm-every-where takes responsibility for buffers-list
Install SLIME from MELPA
Update copyright years
Setup the new flycheck-ocaml syntax checker
Update default opam commands to newest syntax

Newer versions of opam don't do argument parsing of the first argument
after `opam config exec` so everything needs to be passed as separate
arguments in the shell (i.e. unquoted).
