This pull request reintroduces highlighting of hovered annotations which was removed in #4771
I have taken a slightly different approach in the implementation, making it a bit more object orientated.
IsHovered is now a property of an annotation, instead of a global map.
To make this property reactive, using the existing state mechanism, I had to make annotations proper instances of a UserAnnotation or MachineAnnotation class. (Instead of just parsed json objects)
