Make tablist a menu to access different AutoReferee features

[entropitor]

Stuff including viewing inventory, teleporting to a player, to his bed (?), ...

[19:02] authorblues / CW: so the idea is, when youre in the tablist, return control of the mouse to the user (no longer used for moving the view, but mouse is more like in inventory mode). clicking on a player's face teleports you to them, clicking in some other place might pull up their inventory, etc
[19:03] authorblues / CW: the mouse control thing might be kinda funny to work out, but i would guess the rest could be relatively straight foward

Thanks nicka for pointing out!

Currently only for RFW. Need to implement it for UHC still, but should be fairly easy.

Check if it's easy to render the mouse icon differently when over an AutoReferee button.
