// Added a property $ampReplace, this is a quick fix
// it is used to replace ampersands bfore php get a hold of
// the rss file, and replace it once php has dealt with it
// I was getting lines split by an ampersand, pointed out by
// Mathew Clark of Divergent Systems, cheers.
// I will need to address this later on as I deem this fix
// as a bit of a kludge, not nice.
