Feature request - Add Release Date to song attributes

[CAMYR71]

Hi,

I am using the library to load the data into MongoDB to generate some stats about my iTunes Library. An interesting thing to look at is the release date. Could this be added to the song attributes?

I realise that not all entries have it, but might still be interesting to do. Happy to try to add it myself if it helps.

Thanks, Carlos

Hi Carlos, why don't you try it yourself. It should be a fairly small PR!

Apologies for the delay in answering this. It looks like a very simple change, so I will give it a go. I am not super familiar with the GitHub process so, just to confirm what I will dol:

1. Create a new fork
2. Make the changes to the Library and Song files & Test
3. Create a Pull Request.

Thanks!

I made the updates (very similar to the previous pull request for the Disabled attribute!) and created pull request #72

Tested locally, all works fine!
