Add FileType for load autocmd FileType settings.

Hi, nice plugin I like it. But I've got a problem.

I use [jedi.vim](https://github.com/davidhalter/jedi-vim) which is auto complete for Python.
I've Downloaded `jedi.vim` to `~/.vim/ftbundle/python/` and then open python file.
But `jedi.vim` did not work at GUI MacVim.app.
(CUI MacVim works well)

unbundle.vim did not load `autocmd FileType` when ftbundle plugin loaded.

`jedi.vim` defined `autocmd FileType python` at  https://github.com/davidhalter/jedi-vim/blob/master/plugin/jedi.vim#L49
(One of the example using `autocmd FileType`)

IMHO unbundle.vim is heavily related with filetype. A lot of FileType plugin defined `autocmd FileType`.

So, I add `FileType` to `doautoall`.

Please check and include.

Regards,
