Add a port listening option to feed rhonrhon

It uses fixed nickName, channel, server, date for the moment
Add a parsing mecanism to configure the server/channel/date of the feeding logs

Better error handling
Add a feeder.py script which takes a log dir and send all
the log it can find to rhonrhon.

The filename format of the log files can be changed to match any
kind of format
Added get_url_last, AJAX endpoint to list latest posted URLs
jinja2 templating ftw
make URLs clickables
Mandatory license
added jsmacros.html
