Decouple physical and cyberspace worlds

[Norgg]

Currently every building shows up in both the physical world and in cyberspace, without much difference other than what kind of ads you can place on them. Not every building should necessarily be represented in cyberspace, and it'd be good to have a different connectivity between sites than in the real world.

It'd also potentially be good to have a different camera control mode for cyberspace to emphasise the difference, where it's tied to the site you're currently at until you click on a connection to take you to a different one. This could also potentially let you get across the city faster if you hop into cyberspace, take a few long distance links and then hop out again.
