Create cog disabling API (#4043)

* create cog disbale base

* Because defaults...

* lol

* announcer needs to respect this

* defaultdict mishap

* Allow None as guild

- Mostly for interop with with ctx.guild

* a whitespace issue

* Apparently, I broke this too

* Apply suggestions from code review

* This can probably be more optimized later, but since this is a cached value, it's not a large issue

* Report tunnel closing

* mod too

* whitespace issue

* Fix Artifact of prior method naming

* these 3 places should have the check if i understood it correctly

* Announce the closed tunnels

* tunnel oversight

* Make the player stop at next track

* added where draper said to put it

* Apply suggestions from code review
