Subject: [PATCH] Add SwapSides_nogui action

The action is similar to SwapSides, but it
depends on no real GUI, so can have effect when
running an exporter from command line or
with batch GUI.

+/* %start-doc actions SwapSides_nogui
+
+This action shows the opposite side of the board: version
+for scripts when there is no GUI.
+
+Normally, this action changes which pads and silk layer are drawn as
+true silk, and which are drawn as the "invisible" layer.  It also
+determines which solder mask you see.
+
+As a special case, if the layer group for the side you're looking at
+is visible and currently active, and the layer group for the opposite
+is not visible (i.e. disabled), then this action will also swap which
+layer group is visible and active, effectively swapping the ``working
+side'' of the board.
