http not found from customize variables.

[EskoJTH]

There was no option "http" that could be added to org-babel-load-languages if used M-x customize-variable.
worked fine with the elisp at the end of init:
(org-babel-do-load-languages
'org-babel-load-languages
'((emacs-lisp . t)
(haskell . t)
(http . t)))
