[0.4.13][SHELL32] Fix version string in Shell About dlg CORE-16571, & some de-DE

It "regressed" and was displayed cut-off since the switch to git
(our string got longer back then).

Fixed by porting back 2 commits:

0.4.14-dev-976-g 6ce72ba172e69d25e6844244051e467d9d4b1e05
0.4.14-dev-884-g a57f7b50c01efadc50336b5b6664edbf645aff72

and also port back some german translation updates and
trivial whitespace fixes at the same time in *.rc.
