/**
* get news from remote servers
*
* This function queries remote sources and populate the table of links based on fetched news.
*
* On tick, the including hook calls [code]Feeds::tick_hook()[/code].
* See [script]control/scan.php[/script] for a more complete description of hooks.
*
* The function browses the database to locate servers acting as feeders, and read the URLs to use.
*
* A round-robin algorithm is implemented, meaning that servers are polled in sequence throughout successive ticks.
* At most 1 feed is parsed on each tick, to limit impact when the "poor-man" cron mechanism is used,
* which is the default setting.
*
* XML feeds are fetched and parsed according to their type.
* At the moment YACS is able to process RSS and slashdot feeds.
* Link records are created or updated in the database saving as much of possible of provided data.
* Item data is reflected in Link, Title, and Description fields.
* Channel data is used to populate the Source field.
* Stamping information is based on feeding date, and channel title.
* Also, the edit action 'link:feed' marks links that are collected from feeders.
* The anchor field is set to the category assigned in the server profile.
*
* At the end of the feeding process, the database is purged from oldest links according to the limit
* defined in parameters/feeds.include.php, set through feeds/configure.php.
* See Links::purge_old_news().
*
* @param boolean if set to true, fetch news on each call; else use normal period of time
* @return a string to be displayed in resulting page, if any
*
* @see control/scan.php
