* Draw widget name on title bar, posistioning rules will need to be improved !
* Move the name inside the widget and invert it to create like a label
* - Move implemeentation to a 'label' form upper right. Works with all current widgets but Battcheck (that I'll modify acccordingly), moving on, widgets dev know what to expect.
- Possible improvement : fade out label display after 2 secs
* Cosmetics
