/f help - add reference to auto-map

/f map on - Turn on auto-updating map. /f map off - Turn off auto-updating map. To players that are familiar with Factions this is common knowledge, but most new players aren't aware of this. Helpful for finding civ land, but most importantly base-hunting (including when flying with elytra). Only downsides/concerns to listing this (so more players know about it) are that players with it enabled may have difficulty reading chat/miss chat messages, and that it's arguably OP for basehunting when used with an elytra (though you can simply spam /f map, so I'd say this is more QoL)
