Update CodeGenerator so that all Services can have a constructor that accepts RockContext so that two services can share a database connection.  This is mostly just handy when doing Joins.
fix big performance bug in GroupList which was causing production server to max out and become unresponsive (next, sweeping for other blocks that might have same issue)
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
fix bug I missed in GroupList when making the GroupsCount fixes
