(svn r8393) -Fix
-Codechange: CheckCompatibleRail() is only called for tiles which are known to contain a piece of rail. Simplify the function accordingly by eliminating unnecessary checks. -Fix (?): Also fix an inconsistency in deciding what a compatible rail type is between level crossings and other rail tiles. It is unknown if this caused any problems.
