Currently, to_chat is literally just a proc that does user << message.
But it'll let us do output modification in the future, especially for
something like Goon's HTML chat.
Big thanks to PJB for his to_chat script, see
https://github.com/d3athrow/vgstation13/pull/6625 for more details.
closet.dm, costume.dm, decal.dm and window.dm have been knocked out of the define folder and their defines have been moved into appropriate files.
The closet folder has been re-organized a little.
supplypacks.dm has been moved into the datums folder since that's what it is.
