Move SleepSchedule from workers to main bot instance

...and some whitespace cleaning.
This prevents logging in to account before bot goes sleep if bot is launched at sleep time.
And also in my opinion SleepSchedule is not a regular task and it's better to put it into bot directly.

@solderzzc Fixed and tested :)

Can we add console log to tell user the format of conf changed when they have the schedule sleep task configured ? Or, another dev broken help wave will come.

@solderzzc Done.

@cmezh Thanks a lot.

How should the config looks like now?

In the example, SleepSchedule is still under tasks?

@kenkclam It looks like my examples changes were overwritten by soneones PR.
See example here: https://github.com/cmezh/PokemonGo-Bot/blob/03361efd5305bd78be0aebaafd463d5a11fd7628/configs/config.json.example
