NetBeans-JavaFX-Soma: #158


Steps to reproduce:
- Drag and drop the Timeline item from the Animation category to the editor

1. javafx.animation.Interpolator import is missed

2. Unused javafx.animation.KeyFrame import is added

3. The previous Timeline has the  Timeline.INDEFINITE value for the repeatCount attribute. The Timeline.INDEFINITE default value can be easily changed to another.
But it is not so easy to change the 1 value to Timeline.INDEFINITE

4. There is no a Tab traversal for the time and variable values
 ( The same as for Values item. Drag and drop the Values item from the Animation category and press Tab some times)


So the updated template can look like:
------------------------------------------------------
import javafx.animation.Timeline;
import javafx.animation.Interpolator;

Timeline {
	repeatCount: Timeline.INDEFINITE
	keyFrames: [
		at (5s) { slider1 => 100.0 tween Interpolator.LINEAR }
	];
}
