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.
This commit overhauls the examine system to baystation's latest system,
including a more efficient verb approach, and a new status panel tab,
which shows more information for pre-defined objects.
