doc: remove unsued progs and makehtml script, update progs/run

Browse Source 
Due to removal of go_tutorial, unused programs are removed.
        makehtml is unnecessary (it also gives wrong messages when
        the destination file doesn't exist)
        progs/run now compiles all remaining programs under doc/progs.
        Fixes #3076 (again)
