Does not restore the MoveType for in-vehicle players anymore (because if the vehicle disappears, the player may be let in noclip mode)

Fixed invisible NPC ragdolls in single player by adding rag:SetRenderMode( RENDERMODE_NORMAL )

- Original tazer successfully hidden from spawn list.
- Improved the secondary attack sound: better sound, looped sound, no lag, predicted.
- Improved 3rd-person view: increased delay before animating POV.

- Player color is now copied.
- Fixed a possible NPC's ragdoll creation by recreating it manually in case of a failure.
- Sounds have been reduced.
- You will not be able to spawn the (bad) original realrbn's tazer from Sandbox menu.

FAIL: Tried to remove the original tazer from spawn list (because it is useless).

Improved the 'already tazed' security.

Now CPs cannot taze other CPs.

For some reason it happens that the physics object can be NULL on ragdoll creation. I added a check to prevent an error.

Now clients will not create ragdolls for invalid entities (can happen when just joined). Anyway creating them was stupid because ragdolls are removed when ragdoll's entity becomes invalid.
