* sample/CairoSample.cs: bring the code closer to current practice
and update the OnDrawn override to use AllocatedWidth and Height.
Sample now runs cleanly, though with a couple of cairo-sharp bitches
when finalizers run on contexts.
* gconf/GConf.PropertyEditors/PropertyEditorColorPicker.cs :
nuke a GnomeSharp.
* generator/Signal.cs : move eventhandlers and args into the
base namespace instead of a *Sharp namespace.
* sample/*.cs : nuke using *Sharp.
