Quick fixes to tween documentation formatting

Maybe the reST parser should be improved instead though ;)

 	Node useful for animations with unknown start and end points, procedural animations, making one node follow another, and other simple behavior.
-	
 	Because it is easy to get it wrong, here is a quick usage example:
-	
 	[codeblock]
 	var tween = get_node("Tween")
 	tween.interpolate_property(get_node("Node2D_to_move"), "transform/pos", Vector2(0,0), Vector2(100,100), Tween.TRANS_LINEAR, Tween.EASE_IN_OUT)
 	tween.start()
 	[/codeblock]
-	
 	Some of the methods of this class require a property name. You can get the property name by hovering over the property in the inspector of the editor.
-	
 	Many of the methods accept [code]trans_type[/code] and [code]ease_type[/code]. The first accepts an TRANS_* constant, and refers to the way the timing of the animation is handled (you might want to see [code]http://easings.net/[/code] for some examples). The second accepts an EASE_* constant, and controls the where [code]trans_type[/code] is applied to the interpolation (in the begining, the end, or both). If you don't know which transision and easing to pick, you can try different TRANS_* constants with EASE_IN_OUT, and use the one that looks best.
