Bugfix : The date is now correctly parsed in RSS feed. Post formatting is preserved in RSS

A wrong array call would set the date of every entry to 01 january 1970
in the RSS.

Missing CDATA would strip out any formatting from the RSS entry, giving
only plain text in one paragraph.
New : new entry parsing is detected and can be used to trigger specific actions

When a new entry is detected (i.e. the html file didn't exist),
deploySatellite() is triggered.

The function is located in satellites.php and can be used to do
whatever one wants, like posting the new URL to twitter, etc.
