[MIRROR] Bitrunning: Avatars get silly hacker names (#28385)

* Bitrunning: Avatars get silly hacker names (#84279)

## About The Pull Request
Bit avatars now get corny names while spawning in to the virtual domain.
You can change your alias in prefs or have it randomized for s0meth1ng
1337.

Added sechud icons (and thereby orbit ui icons) for bit avatars since
"Cyb3rHaxx0r" might be confusing to find in the living players section.
## Why It's Good For The Game
This was done as a request and after discussion in the code channel.
A little bit of character persistence across simulations.
## Changelog
🆑
add: Bitrunning: You can now choose your hacker alias in prefs.
add: Bit avatars get orbit icons.
