(svn r13531) [NoAI] -Add [API CHANGE]: when building a bridge/tunnel for road/tram, the BuildBridge/BuildTunnel function will now also make two half-road/half-tram pieces on both ends of the bridge/tunnel, so it is easier for you to connect them to your network. This give a more consistant behavior for road.
-Note: if the road pieces failed to build, but building the bridge/tunnel succeeded, the function still returns true (for the obvious reasons)
