Sync more code with upstream, Translations galore, even translations for AntiSpam!

Updated AntiSpam with documentation, safety measures, and better presentations and clarifications for the end-user from FS.
If it looks like something was removed from an xml, it was just moved to fall into place better with v-d.

Corrected log end message being log start message.
