Suggestion: Server tick event

This would simply allow for very accurate timers for various things, such as.

• Golden fish progress timer
• Ability Cooldowns
• Mob Spawn/Respawn timers
  • Terracottas in f/m6
  • Dragons in m7
  • Minibosses in Crimson isles
• Slayer boss/spawn timers could be consistent with server time
  • Various phase timers exist here as well
• Dojo helpers
  There's definitely more here that I haven't thought of.

TPS huds could also finally be very accurate, which is a novel idea.
