Add setStyle and getStyle methods to ol.layer.Vector

Browse Source 
The setStyle method accepts a single style, an array of styles, or a style function.  The getStyle method returns what was set.  Internally, we use the getStyleFunction method which always returns a function.  When calling setStyle, a change event is dispatched (fixes #1671).
