@chennes promised to look at it before this Friday

@chennes here is a reminder 😄

Overall I think this is a great addition -- I've long wanted the ability to have multiple macro directories (right now the Addon Manager has to copy the FCMacro files out of an Addon and install them into the user's macro directory, and this can eliminate the complexity that creates). I think in the long run we'd like this to be configurable via a user-accessible preference, but that can certainly wait for a follow-up PR. So in my opinion this is basically good to go (pending my above concern about the printing code modifying a variable that isn't being passed by reference). But I would like @wwmayer to give this a brief look to ensure I'm not missing something critical about modifying these search paths (which can have unintended consequences).

I am actually working on the declarative configuration way from nix. For now, I implemented the configuration the list of modules, python paths, start-up user configuration file and extra flags for QT. The macros are missing for now, so I needed for this functionality to finish this.

The same config, but FreeCAD 1.1.0dev.39786 not show any macros in folder
