Error occurred while calculating annotation data.
Log Message:	Removed some un-used code from CVS. We can always resurrect this later if someone feels they want to work on it. Gone are the old perl ihost which isn't needed now, winhost which is broken and shows no sign of being fixed, and DBReporter. If someone wants to revive them, I'll undelete them :-)
