-Holograms can move around again. I'm also experimenting with them being area based, meaning they can move around an area freely and lose their hologram when they leave the area. I've made it a const option, so change HOLOPAD_MODE to 0 to return it to the old system, which will destroy the hologram when it is out of range of the holopad.

 		<li class="rscadd">Cameras get upgrades! Currently there's X-ray, EMP-Proof and Motion. You'll find the EMP-Proof and Motion cameras in the normal places (Singularity Pen & EVA), the new X-ray cameras can be found in the Dormitory and Bathrooms, plus some extra ones to invade your privacy.
