Constant rate limiting

[KiOrlando]

Constant rate limiting makes program nearly unusable for anything more than one light

It is annoying, yes. I'll try and find some ways to reduce API calls but I can't really do anything about the API's rate limiting.

Idea: cache the list of devices and provide a nova update command to update the list if needed. Would avoid the need for two API calls (one to get the list of devices, the other to execute the command).
