Icon-O-Matic: Generalize some classes

* Turns PathContainer, ShapeContainer, StyleContainer into Container.
* Makes Shape use Container for storing Tansformers instead of
reinventing the wheel yet again.
* Moves common logic from AddPathsCommand, AddStylesCommand,
AddShapesCommand, and AddTransformersCommand to AddCommand.
* Factors out common logic from two more commands similar to above.
This adds the MoveCommand and RemoveCommand classes.
* Cleans up some code style.

Accept dropping Styles from another I-O-M window.

* Add archived versions of the selected Styles to the drag message.
* If the base class didn't handle the drop message, try to unarchive
Styles and add them via AddStylesCommand.

* A whole buch of refactoring and other changes to make Icon-O-Matic
a multi-document application. This is already more useful than
before, but will be even more useful once it is possible to copy
more types of objects to the system clipboard and paste them into
other open icons.
* Fixed wrong snapping menu item being marked when restoring settings
that enable a different snapping mode from the default.

* Merged weak-symbols branch.
* Fixed trivial merge conflict in src/system/libroot/posix/locale/nl_langinfo.cpp
* Fixed gcc 2 compilation of src/system/glue/init_term_dyn.c.

* added a little bit of tracing to object destruction, since there
seems to be a problem when quitting the app
* added Undo/Redo commands for numerous operations
- (un)assigning VectorPaths to Shapes
- adding new VectorPaths
- removing VectorPaths
- adding Shapes
- transforming Shapes
- adding Styles
- changing Style color
* there was a mix up in classes inheriting from SimpleListView,
RemoveItemList() gives a list of item pointers, not indices
* GradientControl sent the focus notification to the window instead
of the set BHandler target
* StyleView takes care of transfering the current Style color or
the focused gradient stop color to the CurrentColor object, so
the current color of the SwatchGroup is synced
* small improvement to layout of SwatchGroup
* SwatchGroup no longer knows anything about a Style
* fixed syncing the global Selection to the listview selection
at least for ShapeListView
* implemented cloning Shapes
- added Transformer::Clone(VectorSource& source) to all Transformers
- ShapeListView uses this when dropping shapes with shift pressed
* updated NOTES
* added Transformable::matrix_size, so that "6" isn't hardcoded
everywhere (though it still is at most places)
* added listener interface to TransformBox, this is used by
the new TransformObjectsCommand, as long as the TransformBox still
exists, the command modifies the TransformBox transformation instead
of messing with the objects itself
* fixed hotspot size in TransformBox by using the zoom level of
the CanvasView
* TransformBox rotates/scales correctly around the visible pivot
* fixed TransformCommand toggling to transformation (the diff was bogus)
* Gradient doesn't trigger unnecessary notifications in SetColor()
* CanvasView doesn't eat keyboard events when the GradientControl or
one of the ListViews has focus (is a hack currently...)
* fixed bug in PropertyListView when it calls the PropertyChanged()
hook: because of the notification mechanism, the Properties might
be toast after the hook returns
* moved all GetProperty() implementations from headers into .cpp files

drag sorted now)
