Add support to cwm for resizing the windows using Control-Meta-[hjkl].

Please note that this remaps Control-Meta-L (label) to Control-Meta-N (name).

 windows can be moved with the use of the keyboard through Vi-like bindings.
 M-[hjkl] moves the current window a small amount, while M-shift-[hjkl] moves
 the current window a larger amount.
 For example, to move the current window to the left a small amount, press M-h.
 To move the current window down by a larger amount, press M-shift-j.

+Similarly, windows may be resized with the same keybindings with the addition
