Client updates nearby clients more often because they will disappear after 10 seconds without a position update to the client
This results in a massive reduction in unnecessary traffic as we only update clients of their relevance around them
This also resembles live-like packet sending behavior of positions
- Before when reverse aggro checks were done (client to NPC), checks would happen every 750 millseconds where a client would
check an entire entity list with distance calcs and other checks for aggro, with many clients in a zone and many NPC's this would
add a lot of unecessary overhead. A temporary adjustment on 3/25 was made and upped the check to 6 seconds.
- Now, there is a new methodology to scanning. The client will build a cache list of NPC's within close range as defined in new rule:
RULE_INT(Range, ClientNPCScan, 300) and will also get any NPC that has an aggro range beyond that defined range to use in
the frequent checks for aggro, the result is far less overhead
- Client scanning changes when moving versus not moving, the client will scan aggro every 500 milliseconds while moving, and
3000 millseconds aggro check when not moving, with a 6000ms re-fetch for close NPC's
- A demo of these changes can be found here:

- the defaults are set in the code and can be tweaked by sourcing utils/sql/git/optional/rule_values_range_update.sql
- Thanks to mackal for gathering live ranges, thanks to takp for initial numbers
- We would send 200 for combat updates and the client will only display <= range 54 anyways, these should help a lot in spammy combat

Group leader swapping didn't work and left the client in a bad state
This just disbands the group if the leader leaves
Also prevents a group leader from disbanding other groups ...
Which also lead to bad states
Group leader swapping not working is better than these issues :P
