Fine tuning of the whitespace / coding style post processing

The struct / class regex was way too relaxed.
Having the parent class on the same line usually looks better.
clang-format appears to do something odd with continuation strings - even
with UseTab: Always it indents those with four spaces.

Automated whitespace / coding style correction

First attempt to use the tools on one of our source files.
So far so good. Not perfect, but a HUGE improvement.

Most importantly it effortlessly fixed the Allman style braces introduced
in commit 51220f26ef71 ("Add recent files to main menu.").
