libobs: Buffer scene item visibility actions

Browse Source 
This buffers scene item visibility actions so that if
obs_sceneitem_set_visible to true or false, that it will ensure that the
action is mapped to the exact sample point time in which
obs_sceneitem_set_visible is called.  Mapping to the exact sample point
isn't necessary, but it's a nice thing to have.
