interim
tweaked log handling to show "WARNING: "
Added Servifile_globals.yml in ~.
Many changes required:
    * Load config (if it doesn't exist)
    * init
    * init --skip_servifile_globals
    * tests - with monkeypatching ~ and os.path.expanduser
    * debug command
    * update manifest (to handle the fact it is in ~, not MASTER_DIR)
    * update template.copy
