-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.
