Updated some other Grids that might have potential performance issues
+ BinaryFileTypeList - Count was fast, but Sorting By Count could be slow, so rewrote the qry so that SQL would do the work in both cases.
+ BlockTypeList
  + rewrote qry so that Count and Sorting by Count ends up getting done by SQL Count(*)
  + also did some special stuff so that the blocks could be sorted by Status (do they exist as a file)
+ GroupTypeList - Similar change as BinaryFileTypeList.  Count was fast, but sorting by Count might be slow, so rewrote the qry
