ItemManager: Add missing error(...) on parsing failure
Formatting as defined in our astyle.sh rules
.mailmap: switch to Stefan Beller's personal address

Normalize to my personal address. I can still receive email at
the @googlemail.com address, but I tend to use @gmail.com nowadays.

Also add my new corp account.
Note that despite the private address being first,
Google owns the copyright as long as I am employed there.
