functions.inc.php:

- pacrypt(), dovecot:* method:
  - allow "." in dovecot method (to allow a suffix like ".b64")
  - blacklist SCRAM-SHA-1 (needs -u)
  - check against list of non-salted methods to be backward compatible
    with dovecot < 2.1 again
  Thanks to Szilagyi Jozsef <szjozsef AT yahoo DOT com> for providing
  the list of non-salted methods etc.

functions.inc.php, scripts/postfixadmin-cli.php:
- drop unused global variables $table_admin and $table_alias_domain
