util.worldpicker

Hey i just found this file while sifting through the gmod lua libraries, and it isn’t mentioned on the wiki;

Additionally it is only used in one place that i could find:
https://github.com/Facepunch/garrysmod/blob/master/garrysmod/gamemodes/sandbox/gamemode/gui/iconeditor.lua line 143

What’s with that?
Can we get this added to the wiki?

Fresh for you.
