Lights: Changes to light installation & a Borg tool

[aft2001]

I'd prefer for the tool to have 2 modes: Build and Replace. Build just makes a new fixture. Replace replaces a light tube in an existing fixture. Would make it SO MUCH EASIER to fix busted light tubes in a hallway or something.

But otherwise, this is a really fucking important thing that needs to be implemented. Light is 100% necessary for station functions and without it... well you can't do jack shit.
