Cyborg power overhaul

- Medium overhaul of cyborg power usage and charging mechanics. This mostly prevents few issues, such as AFK cyborgs running out of charge when doing nothing or AFK cyborgs in chargers using 75kW of power.
- Refer to specific commits for more information

- This technically implements what currently open PR #6364 implements. Very likely to cause conflicts if both are merged.

- Tested it, should work properly. Might still need balancing.

- Mostly fixes #6358 - It won't reduce the power load, it just evens it out and caps it at 25kW for each charger.
I didn't know about such discussion, either way, if any of the devs wants it can be easily changed back. For me (even if i rarely play sec) it was quite annoying when i was, for example, at Bar talking to someone and everyone could hear that secret info about shapeshifting monster which tried to bomb the SM from sec channel.
