Add icon to geov-entity

[joschne]

The header of a geov-entity should show an icon for some classes (e.g Person, Group, Geographical Place).

As the component can display any class, it must still work for classes that have no icon specified. The alignment of the icon must work on all display sizes.

Added a new component: Entity Class Icon This component return an icon corresponding with class label (Here, a person)

the size is not managed directly, it must be managed by the webcomponent which uses this webcomponent

Here in geov-entity

I'd be delighted to hear your views on the placement of the icon

Implemented for: Person

Geographical Place

Group

Ship Voyage

I added some comments in my pending review to this. I'm going to review the rest of the tickets later - that's why the review isn't finished.
