Fix cg.skulltrails out of bounds access in Team Arena Harvester mode

In Team Arena's Harvester mode, players corrupt your memory from beyond
the grave. Gib the players to stop the corruption!

CG_PlayerTokens is called for player entities, including corpses.
The entity number is used for the index in cg.skulltrails which only has
MAX_CLIENTS elements. This results in incorrect memory being overwritten
for corpse entities (as the entity number is >= MAX_CLIENTS).

So limit skull trails to valid entities (entity number < MAX_CLIENTS).
Make R_LerpTag return qfalse if MDR tag does not exist

Elite Force SDK has trap_R_LerpTag return void, so this shouldn't cause issues for iostvef.
Allows new games to check if a tag exists in a MDR model.

Fix Gauntlet barrel axis in UI

UI's PositionRotatedEntityOnTag is different than CGame's and
UI has switched pitch/roll for Gauntlet/BFG axis to get it to
look like /close to/ how it looks in CGame.

Making UI use the same *PositionRotatedEntityOnTag and axis as
CGame fixes the Gauntlet blade being wobbly in controls menu.
Disable key repeat if key catcher is 0

SDL1.2 branch disables key repeat when key catcher is 0.
Presumably to prevent binds from executing multiple times.

SDL2 replaced being able to disabled key repeat using SDL_EnableKeyRepeat
with a non-zero repeat value in the key event.
