Update toggle_widget.xml

small change 
new interface since we have an ui that is almost useless
we does not need an 1x1 widget without feedback (text), we should use an widget with 4x1 or 4x2 with all features (multi profile(on/off) and text 
<appwidget-provider ends up with /> and not /appwidget>
this also fix update period after widget toogle

We should also remove one of this toggle_widget.xml or onoff_widget.xml. It makes no sense for me to keep them both. Best solution is to use 4x1 or 4x2 widget with text and feedback.
