Remove caption option for KDE .desktop files

some KDE apps have this "-caption %c" in a few variations. %c is "The
translated name of the application as listed in the appropriate Name key
in the desktop entry" according to freedesktop. All apps launch without a
problem without it as far as I can tell, so it's better to remove it than
have to deal with extra sets of nested quotes which behave differently in
each WM. This is not 100% failure-proof. There might be other variations
of this out there, but we can't account for every single one. If someone
finds one another one, I can always add it later.
