WPF NotifyIcon - Release Candidate

This is a NotifyIcon implementation with nothing but WPF in mind. It does not rely of Windows Form’s NotifyIcon component, but is a purely independent control that can be used directly through in code or embedded in any XAML file. Under the hood, there’s quite some Interop (mainly dealing with the Shell_NotifyIcon function and window handles), but the exposed API should be convenient for every WPF developer.
