add wind parameter to character manager and pause VRM springs during pause

[4dispel]

adds a new Vector Setting to the character manager, which sets a wind that will be applied to VRM-character's springbones.
a slight wind could look good on outside venues :)
i made it check for updates to the wind so that animating the wind vector on the character manager can be possible

now pauses springbones during gameplay pauses, before they would move very weirdly during pauses.
the way springbone pausing is implemented in UniVRM is just stopping the updates to the transform so they will still move weirdly it just won't be visible. on unpause they teleport to the location they reached during the pause.
also rebased to resolve conflicts with dev
