New keywords to syntax highlight in C++11

[John Maddock]

Can quickbook please catch up with C++11 and syntax highlight the new keywords?

The complete C++11 list is:

alignas continue friend register true alignof decltype goto reinterpret_cast try asm default if return typedef auto delete inline short typeid bool do int signed typename break double long sizeof union case dynamic_cast mutable static unsigned catch else namespace static_assert using char enum new static_cast virtual char16_t explicit noexcept struct void char32_t export nullptr switch volatile class extern operator template wchar_t const false private this while constexpr float protected thread_local const_cast for public throw
