Add prelude-yaml
Enable prelude-global-helm-global-mode by default

Since Helm is another option to Ido, users who want to use it fully
should benefit from the default Prelude setup. If some users don't like,
they can always disable global Helm mode according to the instructions
in the homepage. User can enable Helm everywhere with
prelude-helm-everywhere.

This change also enables Helm version of command history in shell and
eshell. It also adds minibuffer history without overrides any key
binding in minibuffer-local-map.

Fix prelude-open-with

Currently, `prelude-open-with` does not work with files whose name has a
space or non-ascii character in it. I guess `shell-quote-argument` is
not needed for `start-process`.

I also refactor the code a little bit, and since we dot not care about
the output of `open`, so I removed the buffer name passed to `start-process`
