separate side effects of Clientthink_real

[Razish]

e.g. saber position, inputs etc should update and store a history.
Actual simulation and affects (saber collision/blocking, damage) should be performed each server frame, interpolating with fixed step simulation, similar to unlagged.

This allows capable clients to have a high update frequency without unfair advantage.
See #2 and #5

i think this was tried in sabermod? ask jk2 coders
