[future] - osx template with dynamic src folder

[dimitre]

For the future because it only works on most recent XCode versions, maybe 16+

this brings a dynamic "src" folder that add to compile phase, but at the same time you can choose individual properties in any file (in the case you want to compile a c++ file as objective-c++ for example) it is very useful so you can just create or bring in new files to the project just using finder, no need to add them or re-generate project
