xenadmin/XenAdmin/Commands/ForceVMShutDownCommand.cs
Konstantina Chremmou cad6239c3d Enforce icon size 32x32 on the CommandErrorDialog. Compacted constructors
and removed static method creating the dialog from XenObject; the constructor
can be used for this purpose if the command's CantExecuteReasons are keyed
on IXenObjet instead of SelectedItem.
