-add macros to test for C++ version and features
to catch_compiler_capabilities.hpp
- replaces dynamic exception specifications (deprecated)
with noexcept in C++ Version >= 11
- defines defaulted copy constructor/move constructors/assignment
in C++ Version >= 11 since their implicit generation is deprecated
under some circumstances.
- fixes #259
