Getting the example project to compile, and build.

1) Adding example project to Debug / Release Builds.
2) Including <string> in common.h
3) Using std::optional instead of PowerToysValues::is_[type]_value
4) Fixing warnings generated by unreferenced 'ex' variable in exception handling.
5) Updated relative path of version.h in exeample_powertoy.rc
