Changes to number of products label and removal of scroll view for redrawing - added these to fetchResults so they are in one place only - label was not being removed all the time.  Altered custom product search bug.  Added end dragging method to collectionlistview vc so that arrows properly showed.
Amended test for last page on collection list view so that extra scroll view page isn't added after 2 full rows (6 collections) - also hid the arrows at the start of fetching results so they are then set again correctly.
