Implemented a new map cursor type : Capture Point (little pencil icon on your toolbar). At the moment clicking on the map in capture point mode will cause QgsMapCanvas to emit an xyClickCoordinate(QgsPoint) signal which is picked up by qgisapp and the coordinates are placed into the system clipboard.

In release 0.5 this will be extended to provide simple point vector file data capture / digitising facility. This will be implemented by means of a plugin which will utilise the aforementioned xyClickCoordinate(QgsPoint) signal.
