Ali Mohammad Pur 500044906d LibCore+Everywhere: Remove ArgsParser::add*(char const*&)
This is not guaranteed to always work correctly as ArgsParser deals in
StringViews and might have a non-properly-null-terminated string as a
value. As a bonus, using StringView (and DeprecatedString where
necessary) leads to nicer looking code too :^)
