Martin Hořeňovský 6c5c4c43a0 Add stringification support to std::exception and deriving classes
This support is based on overriden `std::exception::what` method, so
if an exception does not do so meaningfully, the message is still
pointless.

This is only used as a fallback, both `StringMaker` specialization and
`operator<<` overload have priority..
