Issue with translations for splashscreen and plymouth KCM

[Nicolas Fella]

Hi,

in systemsettings there are two similar but different modules. One is
for the splash screen (the thing that shows between entering your
password and the desktop being loaded). That's kcm_splashscreen. The
other one is for the Plymouth boot screen (the thing that shows between
powering on the machine and entering your password). The English name in
systemsettings for the former is "Splash Screen", for the latter it's
"Boot Splash Screen".

It seems that in some languages these names are translated to the same
term, which isn't great since then there are two different but
identically named entries in systemsettings. See
https://bugs.kde.org/show_bug.cgi?id=449338.

Please make sure to translate those to distinguishable names.

Thanks,

Nico
