First stab at a proper README
PropertyChangeBase: Don't try to serialize the PropertyChangedDispatcher
Add options to ActionExtension to control the behaviour if target/action are null
Update Actions to support things like Hyperlinks

Remove tests which were no longer relevant, since Bind/BindWeak refactor
Rename IPropertyChangedBinding -> IEventBinding
Change stylet namespace to https://github.com/canton7/Stylet
