New mini-players for blogs

We have gone ahead and added some much-requested functionality to the mini-players that users can embed into their homepage or blogs. Artsit and track name are displayed now, along with the mixer's username. Also, we have a ringtone facility in there for ringtones to be made and ordered from anywhere the mini-players are hosted.

However the new players are slightly larger than the older ones and so older embedded mini-players may look like they have had their edges cut-off. Sorry about that. We are still in beta, so this is the best time to do these changes - but if you already have a mini-player on your site, you may want to upgrade it to the new one. We'll try not to mess about with it too much after this!
