Merge pull request #108 from mdlayher/master

Formatting and sorting fixes for WaveBox.Server
- Fixed a couple of compiler warnings
- Added synchronous = OFF pragma to database connections
- Refactored folder recursing to be done in the ListOfSongs/ListOfVideos
  methods.  They now have optional "recursive" parameters.
- Adding an itemId to a playlist now figures out what type of item
  you're adding and does the appropriate thing.  i.e. adding a folder id
  traverses the folder structure and adds all media items below it
