Fix for Feature handler uses getFeatureFromEvent on mousemove even without

hover callbacks; r=ahocevar (Closes #1655) 

This means that On the SelectFeature control hover can no longer be set on the
SelectFeature control after the control has been initialized: must be passed at
initialize time. Example has been updated.
