Link to literature

[Abbe98]

I'm thinking about linking to literature about a church by using "described at URL" and "described by source", I think such a section deserves a new header "Literatur" but then we might need to rename "Läs mer". Options that I can think of are "Övrigt" and "Länkar".

I like your idea and think your second suggestion "Länkar" is the nicest one.
