ATS Chat Moss Signal Patch

This patch adds Approach Control signalling on the Alan Thompson Simulation 'Chat Moss' route, where it wasn't already implemented before. Please note that no signals have been replaced so installation of this patch will not have any impact on existing scenarios, this purely utilises the Armstrong Powerhouse Signal Enhancement Pack to add realistic signalling to the route.

This patch includes:

• Approach Control at Edge Hill East Junction when approaching from the Down Chat Moss, for when crossing onto the Down Ditton Fast
• Approach Control in the Earlestown Area, approaching from all three sides of the triangle.
• Approach Control at Winwick and Dallam Junctions for the short stretch up to Warrington Bank Quay on the WCML
• Added missing AWS Magnets on the Up & Down Ordsall Chord aswell as Water Street Junction
