[Chameleon] ROIArea widget

[Julien-Samuel Lacroix]

Hi,

There's a small bug in the ROIArea widget. Go in the following file 
around line 316:
chameleon/htdocs/widgets/ROIArea/ROIArea.widget.php

Add opening and closing parenthesis to updateArea there to have the 
following line in the end:
     goCWCROIManager.RegisterEvent(ROI_CHANGED, "updateArea()");
