split make new baby php cry... EXPLODE instead
Added optional $cache_age parameter to fetch_rss() to facilitate override of defined MAGPIE_CACHE_AGE.
Updated all occurrences of split() to explode() where a regular expression was not necessary. This preps for PHP 5.3 where ereg() and split() functions are no longer bundled.
Replaced deprecated split()'s with explode()'s
