(svn r4373) Rewrite GetSlopeZ_TunnelBridge() and slightly change its behavior:
- Report the correct z alongside the ramp when a foundation is present
- Always report the z under the bridge for a bridge middle part, except if the z hack is used
This should fix some weird behavior of the tile selector near bridges
