basic vibebot (and small rework) (#84143)

## About The Pull Request
this refactors vibebots and reworks them to be a little more useful.
vibebots can now play a range of MIDI songs. they will seek out
depressed players and play an upbeat tune for them and celebrate with
them to cheer them up and increase their mood a little bit. if its ur
birthday, it will play a happy birthday tune for u. emagged vibebots are
ruthless, they will look for sad people and go play grim music for them
to ruin their day even more and decrease their moods.

## Why It's Good For The Game
refactors vibebots into basic bots and gives them a bit more character
