Implemented SetProperty/GetProperty methods for FileControlFrame Added nsGenericHTMLElement::GetPrimaryFrame check for nsnull for doc return type. nsHTMLInputElement.cpp replace NS_OK == with NS_SUCCEEDED in GetValue and SetValue Added GetName and GetValue utility methods to nsFormControlHelper modified nsButtonControlFrame::PaintButton to take the label to paint as an extra parameter. This allows it to be callable from the nsFileControlFrame code to render the button. git-svn-id: svn://10.0.0.236/trunk@20325 18797224-902f-48f8-a5cc-f745e15eee43
