Standardize REPL commands & improve SPC o r

- SPC o r now prompts for a REPL to open when none was found for the
  current buffer.
- REPL handlers must now follow the naming convention "*/open*-repl".
  e.g. +python/open-ipython-repl, +emacs-lisp/open-repl, etc.
- +eval/open-repl has been split in two:
  - +eval/open-repl-other-window
  - +eval/open-repl-same-window
