bug#24224: Enable 'h, j, k, l' key navigation where ever possible

[Mohammed Sadik]

This is a feature request.

There are several buffers where alphabet keys have no effect.
In such buffers, it would be nice to enable the keys h, j, k, and l, for
navigation, and even further q for quit (or close the buffer), o for
other window, etc.  This might also help resolve the pinky problem a little.

The buffers that can include those key for navigation can be
help-mode, apropos-mode, woman, package-menu-mode (package listings),
compilation-mode, customize (Custom-mode), info-mode, and so on.
