ebx: Fix some cg_players.c code mismatch with mint-arena

Two lines had a space at beginning. Two buffer were larger, I recall making them smaller in ioq3 or something.
mint-arena: Have spectator always be in first person

Flying around in third person with no body is weird.

Back ported from Turtle Arena.
mint-arena: Show player team when finished connecting each map

I made it only happen when player first connect to server, but it really
should be shown each map to let people know they finished loading the map.
mint-arena: Expose control of more bot trace contentmasks to Game VM

Also expose pass entity num for AAS_DropToFloor.

To maintain the same behavior in game VM;
  - AAS_DropToFloor: Use passent 0, contentmask CONTENTS_SOLID
  - Others: Use contentmask CONTENTS_SOLID|CONTENTS_PLAYERCLIP
mint-arena: Fix double team change message

Only print team change in ClientBegin if first spawn.
ClientBegin is called at connect and team change.
