A dark theme I've been working on for some time. Based on black plastic 2 by ixlam (http://www.gnome-look.org/content/show.php/Black+plastic+2?content=80092) and with elements of LK_OSX_BB by Lukas87. I'm still having some trouble with the panel. I can't get it to show separators, and it glitches if I assign a background. If anyone knows how to address this, I'd appreciate it.
