		Modified by Michiel
		
		- reacts only on tbody.dataList and tbody.propertyList
		- onMouseMove changed to onMouseOver
		- Added CSSProperty class:
				cg = new CollectionGrid("id");
				cg.addProperty(cssPropName, mouseOverValue, normalValue);
			If normalValue is not set, the last value of the property before the mouseover is used
