Add Dnspod support

export  OPENSSL_CONF so it's used by all openssl commands

Better force_renew

Update template to include USE_SINGLE_ACL

Sometimes certificates are valid for many more years then 1 year.

OPENSSL_CONF needs to be set otherwise the SSLCONF option has no effect on the execution of all the openssl commands.

Added notice about ACL option requirement

Respect -w when using -a

Removed check for ${TOKEN} from dns_del_pdns-mysql, as it appears it …

Added secondary #s to the default config, so that when the lines are uncommented, the function properly.

$WORKING_DIR should always be correct so always passing it along should be the most efficient way to make sure the original -w is respected, right?

-a is still not passing along -f but I'm not sure that is the best thing to do, but I'll make another fork for that.

fix issue #65 to correctly delete tokens.

Added dns scripts for powerdns / mariadb
