Subject: [PATCH] Add ol.control.Control#setTarget

This commit adds a setTarget method to ol.control.Control. This function can be used in cases where the target cannot be set at control construction time. For example, with Angular, it makes sense to create the control instance in an Angular controller, and have a "control" directive insert the control into the DOM.
