* Centralize standard LMMS plugin logo Previously, every single plugin would have its own copy of this image. Now, these plugins pull it from the theme. I'm not sure it's valuable for this to be themeable, but AFAIK it's the place all the other non-plugin resources are stored, so that's where it goes for now.
