Don't use submodule for inf-ruby anymore ?

[stardiviner]

Rinari repository use an old /inf-ruby submodule/. And Emacs add it in =load-path=.
You can check this with this steps:

1. =[M-x inf-ruby]=

2. =[M-x find-library RET inf-ruby]= :: find the loaded inf-ruby library.

3. =[M-x pwd]= :: check out current inf-ruby path.

   I report an issue to inf-ruby repository at Autoloading failed to define function inf-ruby-minor-mode nonsequitur/inf-ruby#48.
   And two relative issue are autoload of minor mode fails  nonsequitur/inf-ruby#46 and autoload of inf-ruby minor mode fails  dimitri/el-get#1622.

Yeah, I'll think about removing all the submodules, and maybe using a Cask file instead.
