[feature] Generate headers

[my-ijet]

add the ability to generate headers like in Makeheaders

[SanderMertens]

Bake already does this:

• When you create a project it generates an include/my_project.h header
• That header includes include/my_project/bake_condig.h
• bake_config.h is automatically regenerated with includes from dependencies

You don't understand!
Makeheaders will generate internal headers, so there is no need to manually create a file .h for each file .c
Just read Makeheaders
