Suggest different default behaviour for daytimes

🙄 Is your feature request related to a problem? Please describe.
In some cases one may want to use automoli to simply switch on and off lights without any different daylight scenarios.
To do this currently you would have to supply a daytime array with a single entry.

😍 Describe the solution you'd like
For me it feels more logically to make this the default behaviour when omitting the daytime array instead of using a default one. I think not supplying a daytimes array shouldn't use a default one but instead just switch the light on and off.
