Implemented #repopclose [distance in units] - Used for development purposes, defaults to 500 units

- Real case use: Large zones with 700 NPC's and you are making fast quick tweaks to nearby NPC's you can refresh just the NPC's around you instead of all in the zone
- This can be quite the time saver
- This command will depop all NPC's and only respawn the NPC's that are 500 units around you or unless you specify otherwise
