add delays to .npc emote repeat

[Erkor 119]

simple suggestion:

 

add a delay function for npc emote <id> r; e.g. .npc emote 1 r 5000 will make npcs do emote 1 (talk) every 5 seconds

 

dunno how difficult this is to code in, but it'd help a lot with the problem of NPCs doing emotes at the exact same time upon a server restart or leaving and rejoining the phase or rezoning
