celestar 9ca761b065 (svn r2595) -Codechange: Introduced "IsSteepTileh" to find whether a tile is steep 
(i.e. spans two height levels) and use it throughout the code.
-Codechange: Add CanBuildDepotByTileh to find if a tile is suitable to
build a depot on it. Wraps some bitmagic which seems quite unreadable at
first glance
