LUA: More control needed over primary entity commands

examples:

--AddPrimaryEntityCommand(Spawn,NPC,"",0,"") -- removes all the primary entity commands (including hail)

--AddPrimaryEntityCommand(Spawn,NPC,"hail",10000,"hail") -- adds the hail command back to the npc

--SendUpdateDefaultCommand(NPC,10000,"hail") -- returns the bubble option when you hover over the spawn/npc

--AddPrimaryEntityCommand(Spawn,NPC,"hail2",10000,"hail2","",0,0,1) -- 1 at the end sets this as a default DENY list, if Spawn is supplied and not null/not player then that player gets default allow access.  Any other players must be added (either by calling the AddPrimaryEntityCommand or subsequently SetAccessToEntityCommand)

--SetAccessToEntityCommand(Spawn,NPC,"hail2",0) -- removes access to the just created hail2 for that player

--SetAccessToEntityCommand(Spawn,NPC,"hail2",1) -- adds access to hail2 for that Spawn (player)

--RemovePrimaryEntityCommand(NPC,"hail2") -- removes hail2 command for all players
