Tutorial 14 - Data Storage

I have finished the tutorials by adding Tutorial 14 for data storage.  This tutorial demonstrates using TrimPath SQL which is included with the engine.  It exposed some issues with data storage objects, which have now been corrected.  Additionally, I've compressed TrimPath Query, and done some renaming to be consistent across files in the "/engine/libs" folder.  This concludes all of the tutorials I wanted to get done for v2.0.

If anyone would like to see some additional tutorials, please let me know in the comments.
