mod_post_msg: Add sendxmpp-curl I wrote this script around the same time as this module. My local copy has a last modification timestamp of 2011-03-29, so it's been unchanged since then. The original rationale was that it seemed overkill to establish an entire XMPP session just to send a single message. Nowadays I'm quite happy using `clix` for this kind task.
