Add player follow mode during demo playback

Browse source 
Call CalculateRanks and ClientEndFrame for the spectator in demo
mode G_RunFrame. SpectatorClientEndFrame copies the followed
player's recorded playerState into the spectator's ps, giving
first-person view with full HUD (health, armor, ammo, weapon).

Standard spectator controls work: mouse1 to cycle, mouse2 to
enter follow from free camera.
