Fix various issues
- readonly(...) should no longer issue errors in bogus manners
- binding for member function pointers and normal pointers should behave better now
- coroutines should now properly transfer the state/identity of their error handlers
- Fix empty base class optimization type
- Improve bind traits metaprogramming
- Add new define to catch-all for exception propagation
- Improve natvis
- Move test defines to build system, as we should
- Add a new example for multiple thread/states in Coroutines
- Add proper direct to mangling in Clang for Windows
- Exceptions are still busted on some platforms (Clang being quite funky)
