The ability to rate tracks from streams

[ngwoo]

Been loving the program so far, and the developer response to bug reports has been fantastic. Just a quick suggestion: it would be nice if we could rate tracks from streams. It may seem pointless to add this, but I often use last.fm streams and radio stations to find new music and it'd be neat if I could go back into the Play History menu and see which songs I rated highly and which ones I didn't in order to check out more from artists I enjoyed.

I'm not sure where the values would be stored, you'd probably need to store them in a new file somewhere.

Thanks.
