Motivation / Problem

Changing something in network/core/config.h took ages to recompile as many .cpp files included it indirectly via settings_type.h or network_type.h even when those .h files did not need it.

Description

Remove network/core/config.h includes from two .h files and add it two three .cpp files that actually need it.

Now changing config.h requires 50 files to be recompiled, compared to 298 before this change.

Limitations

None
