Specify the example configuration is a pocoirc configuration
Added ability to have one blog per channel

... so your bot can sit on many of them and have a different log for

Also updated README example to reflect new configuration layout

Post without title for the time being

UTF-8 titles in POST body makes HTTP::Request::Common complain that
"content must be bytes".  HTML-encoding them means they end up double
HTML-encoded on the site (e.g. "♥" becomes "&amp;hearts;").

So for now we just do title-less posts.
Added log-importer-irssi.pl

... and tweaked its output
fixed double negative logic
