Small update to tweak tab autocompleter and other things
Changes:
Fixed small bug with tab autocompleter that didn't allow second arguments to be autocompleted (e.g. a player's name with /elo check)
Tweaked some of the code to prepare for API access
Only planning to allow reading and modification of player stats, so you could, for instance, make a plugin that does something when a player hits a certain rank, or gets their elo higher than a target, etc.
Fixed small performance bug
Entire list of players is no longer saved to config and then reloaded whenever a brand new player joins
Likely had very little performance impact, but fixed anyway
