	Add support for -fno-exceptions (or equivalent)
This means * Adding new configuration toggle `CATCH_CONFIG_DISABLE_EXCEPTIONS` and a best-guess configuration auto-checking for it. * Adding new set of internal macros, `CATCH_TRY`, `CATCH_CATCH_ALL` and `CATCH_CATCH_ANON` that can be used in place of regular `try`, `catch(...)` and `catch(T const&)` respectively, while disappearing when `CATCH_CONFIG_DISABLE_EXCEPTIONS` is enabled. * Replacing all uses of `throw` with calls to `Catch::throw_exception` customization point. * Providing a default implementation for the above customization point when `CATCH_CONFIG_DISABLE_EXCEPTIONS` is set. * Letting users override this implementation with their own. * Some minor changes and ifdefs all around to support the above
