Improve calc-yank and many other calc setup fixes

- `calc-yank` definition is improved based on the feedback from Jay
  Belanger ( https://debbugs.gnu.org/cgi/bugreport.cgi?bug=21648 )
- Fixed the auto-loading of my modified `calc-yank` definition, now in
  `(use-package calc-yank ..)` form
- Use of :bind and :commands use-package keys for auto-loading
