Profile2: use a different image when no profile is visible

This patch adds a new image resource named poster.png which,
is shown instead of the 3 posters. The main reason for that
is due to the poster text not being visible. This new image
is pretty much the Subsurface logo only.

It also removes the grid lines, while the poster is visible.
