function definition is void: switch-to-js (probably solved)

[drcz]

Dear Kazuki,

Thank you for this great package -- I wanted ``geiser for (js|ruby|python|R)'' and here they are, all in one!
I found a small issue with js support (emacs24-nox on debian) -- it does not work out of the box, complaining about switch-to-js function. Brutal (defalias 'switch-to-js 'js-comint-switch-to-repl) seems to do the trick, but I am pretty ignorant about elisp, so perhaps it's not the best solution?

Best regards!
