Title: Custamizable isearch keybinding

I replaced a not good use of hook to register isearch keybinding.
That was the root of less customizability because
1. nameless function can't be remove by `remove-hook';
2. body, defining keybiding, called each time isearch starts.
For example,
(define-key isearch-mode-map "\C-y" nil)
in .emacs file has no effect. (Overrided by the hook.)
