Signal editing and cost display — Steam Revolution: The Age of Rail Steam update #47431

Display a cost breakdown of the selected objects in the top-right corner. The cost of track that's being drawn is still drawn close to the cursor. Fixed that you could no longer switch/remove signals by clicking them with the signal tool and had to click and press 'X'.Fixed that if no depots were built and you opened the route list for the first time the dialog window for routes wouldn't draw.Fixed that in route editing mode, it was showing the cost of the selected track instead of just the cost of the routes.
