Comment:
MPfm 0.5.0.1
- Added ImportAudioFiles class which will replace the UpdateLibrary process.
  It uses the Reactive Extensions.
  There is still a lot of work to do on the class.
- Bug fixes on MPfmGateway and SQLiteGateway.
- Changed comments/variable names on PeakFile to make it match with UpdateLibrary (and future classes based on the Reactive Extensions)

Comment:
MPfm 0.5.0.1
- Changed the name of the older UpdateLibraryProgressData (now OldUpdateLibraryProgressData, OldUpdateLibraryException).
- This paved the way for the new version of these classes to be used with the UpdateLibrary class (using Reactive Extensions).
- Separated the classes into different file and moved into a proper folder.

Comment:
MPfm 0.5.1.2
- Tested a new method for the new UpdateLibrary process. Seems to work really well.
  It starts X threads to read audio file metadata, waits for all threads to finish, and then inserts the files into the database.
  If there are more files to process it starts again X threads and insert files into the database until the list is complete.
  The downside is that it will insert files into the database often, but the upside is that it seems to work without locking (since
  the mechanism is out of the thread code).

Comment:
MPfm 0.5.2.0
- Added .NET Async CTP Library to the project.
- Player: The audio buffer is now cleared when skipping to a new position or when skipping to a new song.
- Player: The position returned by the player now counts in for the buffer size lag. In fact it is now using the
          main stream output position with a offset position (since the main output position is "infinite" and
          reset to 0 when the audio buffer needs to be cleared).
          It's not 100% done yet though; I need to add a syncmix proc to set the offset position exactly when the
          new song is heard. However the offset is 100% accurate already (since the channel is locked when getting the
          position, and the data available in the buffer is also added).
- UpdateLibrary: The new prototype drops Rx and uses only ASYNC for now. Works fine so far, but the application
                 gets lagged when updating files (especially when generating peak files).
- UpdateLibrary: A prototype UI for the background update library has been added to the main form.
