## About The Pull Request

Bitrunners are now equipped with body cameras. 
The Quantum Console now holds a switch which you can toggle on to
broadcast your body camera footage to the station's Entertainment
Monitors.

I also cleaned up some balloon alerts

## Why It's Good For The Game

I did a gimmick with a bunch of bitrunners and thought it was lame I
couldn't watch them as they did the bitrunning part.
So here we are. I think it is pretty neat and fun, and also kinda
thematic, since it is VR after all.
