CC-3404: Change "Now Playing" dashboard SQL query to take advantage of the "playout_status" field in the schedule table

Browse source 
- Updated the logic in GetPlayOrderRange now I get the previous, current and next shows and tracks to be played.
- This information is then sent back to the caller.
	- if the previous track is null the previous show is sent back as an example of the algorithm.
