Add support for long long and more tests for unsigned long long. https://github.com/vitaut/format/issues/9

Remove IntTraits<uint32_t> because uint32_t is a typedef, not a built-in type. Rename ULLONG to ULONG_LONG for consistency with ulong_long_value. Remove extra whitespace.

Want to be able to format the following without any casting

std::cout << fmt::str(fmt::Format("{:x}") << 0xAEull) << std::endl;
std::cout << fmt::str(fmt::Format("{:x}") << 0xAEul) << std::endl;
std::cout << fmt::str(fmt::Format("{:x}") << uint64_t(0xae)) <<
std::endl;

Document the 'B' type and the difference between 'b' & 'B'. Addresses part of issue https://github.com/vitaut/format/issues/5

Document that "#x" adds prefix "0x" and "#X" adds "0X". Addresses part of issue https://github.com/vitaut/format/issues/5

add support for older GCC versions

Always use noexcept for gcc >= 4.8 because dtors are implicitly noexcept there. Remove binu and 'B' specifier.

Added support for binary modifier
