Fix ESC key behavior

By default the ESC key has bizarre behavior. Sometimes it quits the
thing you're doing, sometimes it completely removes your window layout.
This fixes the issue by defining a new version of `keyboard-escape-quit`
and removing the keybing for `ESC ESC`.

+;; The default behavior of the ESC

+;; name would I want it to close all
+;; my windows when I press it twice?
+;;
+;; This fixes the behavior to do
+;; what ESC should do: "escape" the
+;; current thing I'm doing, like the
+;; minibuffer or a popup window.
+;; ---------------------------------
+
+;; Define fixed version of `keyboard-escape-quit' which does not close
+;; windows or change their layout.
