Update sp_BlitzWho to allow for sleeping SPIDs

declared @ShowSleepingSPIDs as TINYINT but then converting it to NVARCHAR for the dynamic SQL. Was a decision between declaring as NVARCHAR in the first place but I prefer keeping INT values as INT's in the variables. Could change to NVARCHAR so we don't have to convert.
