Allow travel between hub zones/shards via #zoneshard.

[zimp-wow]

Adds zones designated as 'hub' zones to the zoneshard menu allowing for quick teleport between zones and shards provided both origin and destination are hubs.

Change List

• Added 'HubZones' rule which is a comma delimited list of zoneidnumbers for zones that should be treated as hubs. -1 will disable this feature, as will turning of Multiclassing.
• Updated ZoneShardMenu to display hub zones provided player is currently in a hub zone, otherwise will behave as normal.
• Updated automated call to ZoneShardMenu on zone-in to activate if the player is zoning into any hub zone.
• Relaxed rules on #zoneshard to allow teleportation between zones provided both are hub zones.
• Hooked into waypoint script logic to move players between hub zones using waypoints.
  • A script update is required for this to work. Updating waypoint behavior to support zoneshard changes. quests#116
• Added #zoneshardnew command (GMLeadAdmin status required) for spawning new shards.

Testing

This probably needs some testing on the staging/test server since I don't have the Tearal/map stuff set up on mine. I've tested most of the #zoneshard interactions on my local server.

Test Cases

• Zoning between shards in the same zone
  • Works, player preserves current location, player is sent to the correct instance
• Zoning between two different hub zones
  • Works, player is ported to the waypoint location, player is sent to the correct instance
• Attempting to use #zoneshard to zone to a non-hub
  • Not allowed
• Attempting to use #zoneshard to travel to a hub from a non-hub
  • Not allowed
• Disabling multiclassing
  • zoneshard returns to normal behavior
• Disabling hubzones
  • zoneshard returns to normal behavior
• Tearel and map behavior still working as expected
  • Needs verification
