Space Engineers - Update : Projector block, Bugfixing #5

Projector block has been added - players are now able to project blueprints and weld the projection. For more details, please check the Projector Guide below. Note: The projectors do not support blueprints with rotors and pistons at the moment. In case they are used, the projector selects the larges grid and projects only that one. We will continue to work on the projector block - as usual with every new block, this is just the first iteration and work in progress. Thanks for your understanding and for you
