Added query folders to their path. Sorted by dependency.

Added the query folders. 
It wasn't clear where the queries are located. Two were in the concepts folder and others were in firstday folder.
Also, another dependency was observed and added (ventilation-durations).
Sorted by folder then dependency.

 The queries make use of materialized views which aggregate data from the first day of a patient's ICU stay. To run the code, it is necessary to:
 
 1. Run the scripts which generate the constituent materialized views
