Update the way text field is displayed

[rafallus]

Fixed text field displaying the "mouse over" state when already focused.
This causes problems as field is not going to show the focused state until you move the mouse out of the field

The current way is the intended behaviour.
If anything I would change it to always show backgroundOver when field has keyboard focus by modifying that if to:

if (!disabled && style.backgroundOver != null && (clickListener.isOver() || focused)) {
	background = style.backgroundOver;
}

I pushed the change from my previous comment to always show backgroundOver when text field has keyboard focus.

Thanks, that's great. I released that I was not using the style properly and I was trying to modify the code according to my style instead to make my style according to the widget behavior.
