Initial Work on a Soul Network HUD

Tweaked the bars.png texture to make the red LP bar opaque.

Added `NetworkHelper.canPlayerSeeSoulNetwork()`.

Created ISoulNetworkViewer Interface.  Made ItemSigilDivination implement it.

Added ElementSoulNetwork to render the Soul Network HUD.  Registered in Elements.
