What's new in SoapBox Core 2010.09.11?

Version 2010.09.11 includes these changes:

• Should now be able to build to an x86 target
• Improved ability to plug in a custom OptionsDialog and OptionsDialogView (thanks to BSalita)
• New and improved resizable OptionsDialogView.xaml with mouseover effects (complements of BSalita)
• LayoutManager now auto-sets the given document as Active when calling ShowDocument (and ILayoutManager now has IsActive function). Thanks to Lee for requesting this and posting some code.
• Window menu now auto-populates with the open documents, and the active one is checked (thanks to dhm for coming up with the idea and posting some code to get me started)
• Added the CloseAllDocuments menu item to the Window menu
• Added the VMProperty.snippet (vmprop) for making ViewModel properties that implement INotifyPropertyChanged
• IMenuItem now has the IsSubmenuOpen property that is bound from the main menu - great for setting a custom submenu when opening (see an example here)
• Added ConcreteMenuItemSeparator - just a quick way to build a menu separator
• Added the SortAndJoin function to IExtensionService (hint: use a new ConcreteMenuItemSeparator as the joining item when you're making a combined submenu from two imported or constructed lists of IMenuItems - see an example here)
• SoapBox.Utilities now has the IFactory< T > generic interface. Useful for many scenarios, particularly importing an IFactory< Window >.
• Big improvements for creating Context Menus (see examples... still writing them )
• New TreeView ViewModel and View (see this question)
