Update __init__.py

[bmxp]

Some people expierience the Exception: 'Sun' is still above the horizon at [datetime here]. To prevent this I've included an additional sun object to calculate sunrise and sunset. As for my case I didn't get the error again so far ... Also I extended some of the debug logging

Hi,

as Niko is the owner of the plugin he should have the first opinion about the request and should merge it if he likes it.
