Change item name to support queries.

Search pager doesn't seem to allow pages greater than 50.

Item format is now CATEGORY,START,END,QUERY. Eg: "hyves,10,20,voetbal"
will search under /hyves for voetbal and grab pages 10 to 20. Note:
"hyves,,,voetbal" is shorthand for fetching pages 1 to 50 for voetbal.
