Fixes #5413 (Newscasters are no longer floating everywhere)

Fixes #5413 (closed)

Newscasters now require screwdriving after placing on the wall, instead of immediately finishing.

Newscasters are now unscrewed and then crowbared to remove from the wall.

Mapping newscasters remains unchanged from before the issue was presented.

Dmi change includes the unscrewdrivered icon / assembly icon, last two in this image.
