Include after AFC, link scripts/ into the config folder

- bd_pa_spoolman.cfg renames AFC's SET_SPOOL_ID, so klipper-macros.cfg
  must be included after [include AFC/*.cfg]; the README said otherwise.
- install.sh links scripts/ as ~/printer_data/config/klipper-macros-scripts
  so the scripts can be edited in Mainsail/Fluidd.
