No more default password, it is to be set on first connection
Thanks Julien Muchembled for providing crypt function

Conflicts:

monitor: use nexedi account for monitoring static files

no longer in hard development

and rss feed now give weblink to cgi web interface

which show the monitor.json in a html interface

it now also writes all results in the json

Right now, it can run promises and monitoring scripts(manually added),
and create a false rss feed
