Port to pixmaps of the Clearlooks 2 Blend theme for Metacity (http://www.gnome-look.org/content/show.php/Clearlooks+blend?content=56246)

Changes compared to Clearlooks 2:
* Dark border on bottom of unfocused title removed so that title bar blends more with window body
* Dark border on bottom of focused title lightened so that change from unfocused and no line to focused isn't so major
* Outer border of unfocused windows lightened so that background windows are more subtle and subdued
* Partial transparency of title of unfocused windows and subtle pulsing of window buttons on hover
