WPF NotifyIcon

Browse Source 
--------------
CHG   Changed show/hide functionality in order to work better with showcase window (which is no longer the app's main window).

git-svn-id: https://svn.evolvesoftware.ch/repos/evolve.net/WPF/NotifyIcon@105 9f600761-6f11-4665-b6dc-0185e9171623

CHG DataContext is also assigned to ContextMenu, and properly coerced for
ToolTips and Popups. Also checks whether target item has a binding
on the DataContext (does not just override if DataContext is null).
Thanks Nic Pilllinger for pointing this one out.
CHG Popup creation no longer calls Popup.CreateRootPopup which tries to
bind to dependency properties that do not exist, thus causing debug
warnings. Thanks to Loic Berthollet for the hint.
CHG The LeftClickCommand now executes with a delay in order to mak sure
it's not a double-click.
FIX Removed debug output in WindowMessageSink.
