Teo-CD ddb01d0509 World: Clean warnings, optimize GetBlock
World has a lot of type conversion warnings. Take care of most of them,
for a slight performance hit ( :( ).
Re-order constructor parameters to match declaration.
Move FillColumn to a more appropriate place.

GetBlock gets called a lot : use direct memory access of the vector
rather than going through bounds checks with .at().
Introduce an integer overload to remove warnings.
