Update interval too low, vessels stuttering at low distance

[nux17]

Vessels are stuttering when controlled by a player and seen from low distance.

I guess we should increase the refresh tickrate (5hz atm), or put it in the options.

Would do a PR for this, but can't figure where the tickrate is set.

Yeah, the update rate should be configurable.

I agree that it should be adjustable in the server settings.
