Martin Hořeňovský 7e4038d848 Capture std::clog writes and combine them with std::cerr writes (#989)
This also introduces Catch::clog() method to allow embedded targets
to override std::clog usage with their own stream (presumably null-sink),
similarly to how Catch::cout() and Catch::cerr() are used.

Fixes #989
