Swept:
`-Wpadded` in some places (where it caused extra size, instead of just
saying "hey, we padded struct at the end to align, just as standard says")
`-Wweak-vtables` everywhere (Clang)
`-Wexit-time-destructors` everywhere (Clang)
`-Wmissing-noreturn` everywhere (Clang)
The last three are enabled for Clang compilation going forward.
Also enabled `-Wunreachable-code` for Clang and GCC
- updated command line setup with new API
- updated STITCH macros
- force embedded Clara to use Catch’s console width (but restore it after)
- remove command line tests (as these have now moved into the Clara project)
- Clara now built with new stitch script (based on generateSingleInclude)
- also fixed python scripts for python 3 (print now a function rather than a keyword)
- This is just a first step. It still has a dependency on catch_text.h, which also needs to be made a Cliche header.
- These then need their own homes on GitHub.
