Rework albumart buffering internally to allow for mutliple albumart sizes.

Playback now has a few albumart slots. Anything (most importantly: skins)  can obtain such a slot.
The slot has fields for the size which is passed to bufopen then to image_load to buffer the albumart with the proper size.
Currently there's 1 slot. We can increase it for remotes if we want. Custom statusbar will increase it.
