moved "scripts" folder to "config/autostart"

All cfg-files in config/autostart get executed during startup.

- more appropriate directory name and place
- files are now sorted alphabetically, as promised
- doubles are removed (resulting from identical file names in home and
  install tree) since they would only result in files run twice
- scripts with file names prefixed with "_veryfirst_", "_beforesaved_"
  or "_aftersaved_" will be run as very first config file, right before
  saved.cfg or right after saved.cfg
- all remaining files will be run right before autoexec.cfg
- the directory "config/autostart" will be created, if it doesn't already
  exist in the home tree
