gm_skyvoid

gm_skyvoid is a 16384x16384x16384 box with the tools/toolsskybox2d material.
There is a semi-transparent platform (which is also near the map's origin) for players, as well as a completely invisible world brush in a case that platform is gone for some reason. There are 25 info_player_starts (player spawn points) on the platform.
The sky and sun parameters were copied from gm_construct. it just looks so good
The map sky name is painted, so you can use the sky editor. If you wish to make the map a black void instead of a sky void, simply set the sv_skyname console variable to black. Set it to painted again if you want the sky back.
