Bilder im Kopf - merge

[Pavelus]

Hello, please fix this:

1) there is a bug in book name:
"Bilder im Kopf. Die Geschichte meines Lebens." - no dot at the end (check the book cover)

2) combine these two book entries into one:

https://www.goodreads.com/book/show/2...

and this is fourth edition of the same book like above, but for some reason not combined already. Data fit.

thanks in advance.

Done! Some of the changes may take longer to show.
