Enabling/Disabling Debug Nodes as Setting

[stellarpower]

Unstable / deprecated nodes are removed by a macro in the build:

#ifdef PRODUCTION_BUILD
		if (node->IsDeprecated() == true || node->IsUnstable() == true)
			continue;
#endif

This is a sensible default, but, it would be nice to make this a tunable parameter in the settings, so this can be edited without recompiling. I tend to avoid training using the debug builds, because when they fail an assertion (and they always do eventually - this would also be good as a setting I can tune with e.g. environment variables), it aborts and kill the whole program. Meanwhile, there are nodes not enabled in the release build I would like to add to my nice shiny new protocols!

Thanks
