Add "edit" icon to contacts

[JoeyStk]

Describe the Bug

For pages, events and POIs we have an additional icon for editing. For contacts we don't have that yet. After UI/UX testing it was wished for sake of consistency to add the icon to contacts too

Steps to Reproduce

1. Go to 'pages
2. See icon "edit"
3. Go to 'contact'
4. See it's not there

Expected Behavior

Consistency between the content types

Actual Behavior

Icon missing for contacts

Additional Information

None

@JoeyStk
Do you mean the pensil icon in the column "Options" in the page/POI/event/contact list? It exists only in the page tree if nothing is missing in my environment. Do we introduce it in all the list views?

[JoeyStk]

Yes, I mean the pencil. I assume that we would introduce it to all list views, but this is probably a question for @nikolahoff :)
