Add to template, repl, vim sections

New:
  clj-jade (template), fipp (pretty printing), reagent, om,
  vim-redl (repl), vim-clojure-static, vim-sexp (like paredit)

Updated pointer to new locations for boot and pallet.

Added midje to continuous testing since not obvious it solves that problem.

Consider removing vimclojure since author now endorses fireplace:

Would also be nice to go through github's top cljs projects for inclusion, but
I'm not really using any yet to be able to recommend.
