Improve Helm configuration

The current prelude-helm only uses a single command of Helm, which
is a waste given how Helm contains many other commands. When
prelude-helm is activated, users should be able to utilize all of these
useful commands. If a user wants to use Helm, he will want to use all of
its features anyway.

prelude-helm is configured that it is able to be used with this [guide](http://tuhdo.github.io/helm-intro.html).

Allow enable/disable global helm key bindings

Since some users prefer using default Prelude commands, a new global
mode is defined: prelude-global-helm-mode. When activate, Helm binds
some global key bindings to its own commands. When deactivate, Helm
removes the bindings and Prelude uses the default bindings.

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.
