Do not auto indent in conf-mode and yaml-mode
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`

Adjust Helm prefix key

helm-command-prefix-key is already defined with defcustom in
helm-config.el. It must be set before helm-config.el to take
effect. With current setting, "C-x c" is used instead of "C-c h" and it
conflicts with the guide on homepage. "C-x c" makes it easy to press
"C-x C-c" to close Emacs when pressing fast enough. "C-c h" is also
originally used for Helm in Prelude.

Adjust Helm prefix key
Set prefix key before loading helm-projectile

Because helm-projectile loads helm-config, prefix key must also be set
before helm-projectile. Comment is added for future reference
