pub info for books in journal field

[annetteholtkamp]

Expected Behavior

The publication info for books should appear in the 260 field

Current Behavior

Lots of older books have their pub info in 773__x, usually in the form
773__x:Cambridge, Uk: Univ. Pr. ( 1985) 376p
Sometimes series info appears in parentheses at the end, e.g.
Berlin, Germany: Suhrkamp (2012) 481 p, (Suhrkamp Taschenbuch Wissenschaft 2033)

Steps to Reproduce (for bugs)

Context

Results e.g. in wrong bibtex entries.
It should be checked whether the info in 773__x is already present in 260, 300 and 490
