Update doctest.h because the old version causes build failures on Linux.
Also move it from third_party/include/doctest to third_party/include.

Switch usage of std::optional to nonstd::optional for now because of an
error from the Mac builder script, I cannot reproduce the problem yet
but will try to fix it later, it may not be fixable when targeting 10.7.
The header is from:
https://github.com/martinmoene/optional-lite
.
Usage is about the same, to include:
`#include "nonstd/optional.hpp"`
Then use nonstd::optional and nonstd::nullopt instead of the std::
counterparts.

Add the Catch2 headers to third_party/include/catch2.
Add Catch.cmake and CatchAddTests.cmake to cmake/.
Add unit tests src/wx/tests/strutils.cpp using Catch2 to test
src/wx/strutils.cpp.
Make some code changes to strutils.cpp to make the tests pass.
See src/wx/tests/CMakeLists.txt for how to set up unit test files; they
plug into the normal CTest mechanism in cmake.
The test binaries are written to the tests/ subdirectory of the build
directory.
Building the tests and enabling the CTest support can be turned off by
passing -DBUILD_TESTING=OFF to cmake, the default is ON, this is the
standard mechanism.
Start running ctest on travis and appveyor.
Move stb to third_party/include where Catch2 is now as well.
