Various improvements to the benchmarking support

Browse Source 
* Units from <ratio> are no longer redeclared in our own namespace
* The default clock is `steady_clock`, not `high_resolution_clock`,
because, as HH says "high_resolution_clock is useless. If you want
measure the passing of time, use steady_clock. If you want user
friendly time, use system_clock".
* Benchmarking support is opt-in, not opt-out, to avoid the large
(~10%) compile time penalty.
* Benchmarking-related options in CLI are always present, to decrease
the amount of code that is only compiled conditionally and making
the whole shebang more maintainble.

CATCH_CONFIG_WCHAR // Enables use of wchart_t
CATCH_CONFIG_EXPERIMENTAL_REDIRECT // Enables the new (experimental) way of capturing stdout/stderr
CATCH_CONFIG_DISABLE_BENCHMARKING // Disables the compile-time heavy benchmarking features
CATCH_CONFIG_ENABLE_BENCHMARKING // Enables the integrated benchmarking features (has a significant effect on compilation speed)
Currently Catch enables `CATCH_CONFIG_WINDOWS_SEH` only when compiled with MSVC, because some versions of MinGW do not have the necessary Win32 API support.
