FIXES #801

Idea from #267

Fixes typos in template domain.cfg

RFC operations for account security:

--new-account-key replaces the account key with a new one.
  Can modify the type or size as well. (update .cfg first)
  Does not affect certificate validity or pending operations.

--DEACTIVATE-account permanently deactivates the account on
  the server.  Per RFC, can not be revived.  Should not revoke
  existing certificates. (Server's choice.)

Also fixes bug that caused previous registrations to be invalid.

See issue #840.

This is useful for debugging; it leaves any tokens in the DNS &
records its environment.

It's only meaningful for debuggers (and some problem reports
for which ask for them.

FTP_PORT not used by ftp.

No code for sftp, davfs, ftpes, or ftps.

Needs tests, but at least this won't fall thru to attempting to delete
from local file system.

Verifying PostgreSQL certificates requires setting the protocol type for s_client as it is not plain TLS, but behaving more like StartTLS in other protocols.
