not prediction but reduce lag caused by the absence of it

fix conflict with my own mod lol

- Removed realistic falldamage in the mod itself. Use mp_falldamage 1
- Added sv_combatroll_maxspeed_offset. Copied from its description: "On landing if you have higher speed than a certain value, you wont be able to roll and you will die. You can offset it and save yourself! (only works with realistic fall damage enabled. otherwise you can roll always)"
- The ability to roll gets decided by calculating the fall speed that will definitely kill you and not allowing to roll if your speed of landing was higher than the calculated value. As stated in the previous point you can offset it and it doesn't apply to mp_falldamage 0

rewrote the whole thing
