add coordinate system name to ArcMap status bar

Idea created by tormsby-esristaff Employee on Feb 9, 2011
    The ArcMap status bar reports the map units of cursor location, but it doesn't tell you what the coordinate system is. It seems like there's plenty of space here and it would be convenient to see the data frame's coordinate system reported here, too, either in front of the map units or after them. Or at least make this an optional setting on the Data Frame Properties General tab.
