Re-Add shortcut API for finding tile bounds

[nightm4re94]

With 3a01c22, the convenient methods to find tile bounds were moved to IMapOrientation. Accessing these methods in a non-static way is far more tedious, as the comparison below shows:

Syntax before:

MapUtilities.getTileBoundingBox(Point2D targetTile)

Syntax after:

Game.world().environment().getMap().getOrientation().getBounds(Point2D targetTile, Game.world().environment().getMap());

We should add static shortcuts again that call the instance methods for the current MapOrientation.
