Compiler: adding hooks (custom recipes) between the main phases. New hooks are:

hooks.sketch.prebuild, hooks.sketch.postbuild, hooks.libraries.prebuild,
hooks.libraries.postbuild, hooks.core.prebuild, hooks.core.postbuild,
hooks.linking.prelink, hooks.linking.postlink, hooks.objcopy.preobjcopy,
hooks.objcopy.postobjcopy, hooks.savehex.presavehex, hooks.savehex.postsavehex
