Reload team bot lists

[VirxEC]

• If a player is not a custom bot, it always gets added to the list
• If a custom bot is not found, it gets removed from the list
• If a custom bot was given a custom name, that name is preserved - otherwise, the display name is updated
• Order of players in the list is preserved
• UUID of the players are preserved

I tested this and it appears to work pretty well. Fixes #49

looks good
