Missing functions for some devices in verse

I noticed some functions for some devices are not exposed in verse, these should be added. Because now I have to use a workaround of adding a channel device to trigger these functions.
Here are some missing functions:

changing_booth_device:
Enable()
Disable()

visual_effect_powerup_device:
Clear(Agent:agent)

player_spawner_device:
SpawnPlayer(Agent:agent)
