* reporting/fgraph.php: Fixed bug where a graph wouldn't return
when free search was specified. Also made SQL safer against
attacks since fgraph can be accessed by anyone. This should be
fixed in later versions so there has to be no SQL query passed
* operation/events/events_rss.php: Made RSS feed better. Now you can
also pass a filter from events.php. Fixed direction of the links
* operation/events/events.php: Added a filter on agent name. Updated
for RSS feeds. Added filter on event id
* install.php: A little bit of automatic field filling. Corrected some
text for more correct English and update to the new URL specification
