New script: irclogs.py

Generate IRC log archive pages for mantisbt.org based on files saved by
mantisbot / ChannelLogger plugin

Processes the Supybot ChannelLogger's log directory, generates html
pages for the IRC logs (assumes no leading '#' on filenames) using
Marius Gedminas' logs2html script [1], and copies them (rsync) to the
webserver's directory.

See [2] and [3] for further details
