many improvements and bug fixes:
* added VertexSource::SetLast() used by PathSource
to call agg::path_storage::close_polygon(). The
StrokeTransformer avoids this of course. Affine
and PerspectiveTransformer forward this to their source.
* TransformerItems watch their transformers for notifications
* made VectorPath an IconObject
* VectorPath no longer uses close_polygon() when converting
to agg::path_storage to allow open strokes
* added IconObjectListView which inherits from
PropertyListView and allows to edit the properties of the
last selected object from one of the other list views
* fixed a couple bugs when adopting properties:
- removed the Property* in the PropertyEditorView base
class, and made GetProperty() virtual, as the base class
pointer was not maintained and superfluous
- delete the old PropertyObject in PropertyListView::SetTo
when adopting the properties instead of the object whose
properties were adopted...
* added SetPropertiesCommand to allow Undo/Redo on changes
of properties
* Style is also an IconObject now (TODO: yet another list view
for styles... :-)
* Style watches its Gradient for notifications and builds and
caches the color array now
* removed generating the color array for each scanline in
IconRenderer, so the performance is improved a lot
* Shape watches its Transformers for notifications in order
to trigger rerendering
* StrokeTransformers adds a bunch of properties like stroke
width, cap and join mode
* StateView keyboard filter no longer steals keydown events
from BTextViews
* PropertyItemViews resize with the parent
* refined the interface for PropertyListView for easier
tracking of the changed properties in derived classes
* added HasPendingNotifications() to Observable, so that
IconObjects can track changes more easily when adopting
a PropertyObject
* the name is now part of any IconObject

added extensive "PropertyObject" framework
* Property is an abstract class for representing some property with
an interface for setting/getting the value and cloning
the property and such stuff
* PropertyObject holds a bunch of different Properties
* various specific Property classes represent floats, integers,
colors, booleans, options and so on
* PropertyListView can edit the different properties in a
given PropertyObject by using individual property editor views

The plan is to be able to convert some random object (for example
a selected Shape or Transformer, Style or whatever) into a
PropertyObject for being edited in the PropertyListView like it is
done in WonderBrush...
