[dwm] ntile layout for dwm hg tip

Hi there,

I have adapted the nmaster ntile layout for the current dwm
hg tip. Maybe it could be useful for someone else.

You should modify config.h to include (after setting RESIZEHINTS):

#define NMASTER 1
#include "nmaster.c"

Add a new "ntile" layout

        Layout layouts[] = {
                ...
                { "-|=" , ntile },
                ...
        };

and, finally, two new keybinds:

        { MODKEY|ShiftMask , XK_j , setnmaster , "+1" } ,
        { MODKEY|ShiftMask , XK_k , setnmaster , "-1" } ,

I have adapted neither cpt nor tilecols. Of course, thanks for your patch
pancake.

Kind regards,
Nibble
