This patch replaces the originally included AP front destinations and replaces them with a much more accurate font. 
Included in this patch are: 
Newly created front destination font applied to all liveries. Correctly shaped and positioned Class 379 Front Destinations - also now includes 'Stansted Express' destination option. This is found after 'Stansted Airport' in the original list with the other final dests continuing on after.  Destination codes and list is as before thus not affecting scenarios. Note- Destinations in scenarios using the Class 379 will be affected after 'Stansted Airport' due to the new addition of 'Stansted Express'. Known Issues:
Due to there being a limit on the amount of side destinations available on the Class 379, I have had to sacrifice the 'Special' Destination Option on the sides of the train to make way for the 'Stansted Express' Destination. Note- this does not apply to the front destinations, these still retain the 'Special' Destination, only the sides lose this.  Credits:
