Fixed bug with NPCs. (Games tried to uses a NPC Head as your Head. -> Block flies towards NPC)

Switched from Vector3 to Vector3D for higher percision. (better behaviour at large corrdinates.)

Added a Option in the Config to enable/disable the debug messages (also errors) [default=off]

Changed Raycast to a List. If the first thing can't be picked up, it will try to pick up the thing behind it.
(for example a Block behind a Wolf)

Disabled Error Messages for the Client to Host Packages as a fix to a problem.
Small Lag spike could still happen!

Workaround to totally avoid the problem would be to let the grid to shortly before the blocks merge so the host can still recive the message that the client let go and remove the grid from the hold grids before it gets deleted (in the merge process)
