An alternative to the unity build, the classic build compiles each translation unit individually. This adds more modules to the classic build: * Remove unity header app.h * Add missing includes as needed * Remove obsolete NodeStore backend code * Add app/, core/, crypto/, json/, net/, overlay/, peerfinder/ to classic build
