Model recompile on windows and MacOS

[Bandsberg]

Changes recompile to 'save file event'.

Solves some of the issues related to #12, as the model recompiles and reloades on Win10 but only recompiles on MacOS.
The issue of reloading model on MacOS does not appear to be related monitoring of/watching for changes to model files.

Also added Debug settings for codeLLDB VSCode extension. Maybe that should either be removed or added to VScode as a suggested extension?

Thank you, @Bandsberg, looks great! I also just tested this on my machine, and can confirm that it still works on Linux.

There's one problem: Two rebuilds are triggered for the same modification. The second rebuild barely takes any time though, so it's only a minor annoyance. And that it works on more platforms is more important anyway.

I'm going to merge this and will open a separate issue for the multiple-rebuilds problem.

Okay, as usual I forgot to reply to something.

I'm not using a debugger right now, but I'm fine with merging configuration that is used by regular contributors, as long as it's not too disruptive otherwise.

By "suggested extension", do you mean Recommended Extensions? I haven't used this feature before, so I'm not sure what to do here. Would that mean that every VS code user would get a pop-up about this extension, or something? If so, I don't think this is necessary.

I do and yes there would be a pop-up. Roger that 😄
