pre/post_processing_commands required in settings files

[chippydip]

If build_parameters is included in the user or project settings files and doesn't have both pre_processing_commands and post_processing_commands then builds will silently fail. This is unintuitive since those settings are supposed to override the defaults (which should be an empty list in this case). At the very least it would be nice to get an error message in the console.

Looks like a simple check in the build.js file before trying to loop over these arrays should fix the problem.

Hello,

Yes current behavior is not great, it should be an override/inherit behavior for the settings. I will look into that.
