Revenants can change their name [OCULIS PORT] (#5768)

## About The Pull Request
**PORT OF https://github.com/Monkestation/OculisStation/pull/129.**

Allows revenants to choose their own name or use the default name.
## Why It's Good For The Game
This allows for more roleplay opportunities as you can now run with a
potential gimmick without needing admin intervention. There is also
precedent with antagonists being able to rename themselves due to Space
Dragon.
## Proof Of Testing
See below.
