Rewrite ^pull logic and handling. **MORE**

Add ^setassistee command to set who your bots will assist. Bots will always assist you first before anyone else.

If the rule Bots, AllowCrossGroupRaidAssist is enabled bots will assist the group or raid main assists.

Rewrites logic in handling of pull and returning to ensure bots make it back to their location.
