Column.toString now uses WorldTree.absoluteName
ResolutionEngine.resolveQuery was bugged

It was possible to specify conditions to queries that were
either not handled or handled in a wrong manner.

Now, conditions are checked after the basic query is resolved.

This is only a temporary fix as this approach is inefficient
Modified WorldTreeFactory.fullInit

WorldTreeFactory.fullInit now works by calling
    - initRooms
    - initRegions
    - initTiles
    - materializeConstraints
    - fill
