Correct allowed rotation for placed objects

[stilnat]

Summary

This introduce the possibility to have custom rotation while placing object with the construction menu. By default, tile objects have four possible directions. I wrote a bunch of scripts that can be added to prefabs to allow for custom rotation. it can limit it or add more possible directions, but possibly also add complex rotation behaviour such as :

North-South-East-West-NorthEast-SouthWest-North....

this is a nonsensical example but just to illustrate the freedom.
Currently, there's only one script that allow only checked directions to work.
