cyclelayout crashes when it reaches the last layout

[0xGodspeed]

Happens in reverse order as well.

	{ MODKEY|ControlMask,           XK_comma,      cyclelayout,            {.i = -1 } },
	{ MODKEY|ControlMask,           XK_period,     cyclelayout,            {.i = +1 } },

Presumably you still have the NULL layout in your config that used to mark the end of layouts. You can remove that and it should no longer crash.
